This CL removes the roots section from the rust-projects.json file as it
is no longer required by the rust-analyzer tool.

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.
