Previously, the sdk snapshot would include all the entries from the
stub-flags.csv and all-flags.csv modular files generated by a single
bootclasspath_fragment. That included implementation details, i.e.
class members that are not part of a stable API or the hidden API which
meant that the sdk snapshots were implementation dependent.
This change removes the implementation details from the modular flag
files, i.e. those entries that are only marked as "blocked". When
comparing the files against the corresponding subset of the monolithic
files it assumes that any entries missing from the modular flag files
are blocked.

This serves to not link parts of soong_ui (and eventually soong_build)
into a separate, weird binary. This is in turn good because they contain
any number of global variables and no one really thought about what
happens when two instances are executing at the same time in the same
address space.
This comes with a slight performance hit: 5 aosp_* projects build 152
seconds instead of 146. I suppose this is a price worth paying for a
clean design?

Previously, the signature-patterns.csv file included a lot of
implementation details, e.g. the signatures of dex members or inner
classes that are not part of any API, including the hidden API.
This change will remove all member signatures and inner class names
from the file and replace them with just the outermost qualified class
name.
That will still leave some implementation details, e.g. the names of
implementation only classes and packages.

Previously, a simple map from dex signature to the flags was used to
store the monolithic hidden API flags. This change replaces that with a
trie that uses packages and class names extracted from the signature
to map from the signature to the flags.
The signature is broken down into pieces consisting of package names,
class names and the remaining member signature. They are used in turn
to navigate through nodes in the trie to a Leaf that contains the flags
associated with the signature.
The flags can be retrieved from the trie in a number of ways:
* Using the complete signature to retrieve the flags for a single
member.
* Using a class name to retrieve the flags for all the members in a
class and any nested classes.
* Using a package wildcard to retrieve the flags for all the members in
the classes in that package.
* Using a recursive package wildcard to retrieve the flags for all the
members in the classes in that package and nested packages.
This will allow a bootclasspath_fragment to select a subset of the
monolithic flags to compare against itself without specifying the
signatures of every member of that set.
Before creating the trie an attempt was made to compute the subset by
iterating over all the signatures in the monolithic flags and matching
against a regular expression created from the patterns but that was too
slow. It took minutes to run whereas using the simple map or the trie
only takes a few seconds.

- If no system_shared_libs is specified, bp2build writes no attribute
value. In this case, the bazel library macros determine the correct
default behavior.
- If any system_shared_libs is specified for any variant, then bp2build
writes the value verbatim. This includes if an empty list is specified,
as this should override defaulting behavior.
Note this defaulting behavior is incomplete and will be incorrect in
corner cases. For example, if, in an Android.bp, system_shared_libs is
specified for os.linux_bionic but not for os.android, then the bazel
default for os.android will be incorrect. However, there are no current
modules in AOSP which fit this case.
As a related fix, supports static struct for cc_library_static.
Also, removes some elements from the bp2build denylist.

Previously, the signatures used to select the subset of the monolithic
flags were simply the signatures read from the modular flags file. This
change moves the creation of the signature list into a separate script
that outputs the signatures to a file and then passes the path through
Soong from the bootclasspath_fragment modules that create it to the
platform_bootclasspath module that uses it to compare the modular
flags against the monolithic flags.
Currently, the signatures are the full signatures but follow up changes
will replace them with patterns (hence the name) that avoids having to
include implementation details in the hidden API flags that are output
as part of a bootclasspath_fragment's snapshot.
This change moves the stub flags related code next to the all flags
related code as they are treated in a similar way.

R8 will parse proguard files out of resources in injars. Use the jar
with resources instead of the classes jar so that R8 can see the
proguard files.
R8 fails when an input jar contains dex files, so filter out dex files
from the input jar before passing it to r8.
This relands Ibb870ee9c70470336f542a3b7542dab86716dbf8 with a fix to
move the temporary input jar outside the output directory. Putting it
in the output directory interacted poorly with RBE in local comparison
mode, which incorrectly deleted the output directory.

Previously, the compare_signature_flags compared the full set of
monolithic flags against the modular flags and just ignored any
monolithic flags for a signature that was not present in the modular
flags. It essentially performed two tasks, identifying the subset of
the monolithic flags against which the modular flags should be compared
and then doing the actual comparison.
This change separates those two tasks, by first creating a dict that is
the subset of the monolithic flags against which the modular flags will
be compared and then do the comparison.
At the moment the subset is simply the set of monolithic flags
associated with the signatures that are present in the modular flags.
Follow up changes will provide other ways to select the subset.

Refactor verify_overlaps to make it testable and add tests for the
comparison. It does make one significant change in behavior which is to
read each of the files produced by a bootclasspath_fragment into a dict
before comparison, rather than reading and comparing them a row at a
time. That allows it to reuse the code to read a CSV into a dict.
