The wrapper to getenv() appends the effective userid (euid) of the
current process to GCOV_PREFIX. This avoids conflicts and permissions
issues when multiple processes try to create/access the same directories
and files under /data/misc/trace.
Test: Verify that coverage files are written to
/data/misc/trace/<euid>/proc/... instead of /data/misc/trace/proc/...

Previously, the libprofile-extras dependency was added as a
LateStaticLib and the constructor in this library was included during
linking with the '-uinit_profile_extras' linker flag. This was done
because at the deps() stage, the exact binaries that need coverage are
not known (in fact the coverage-enabled variants are not created yet).
This meant that for a link command, if one of the shared libraries
already exported the constructor, the output of the link command did not
load/link libprofile-extras.
For other reasons, we now want to add more symbols to this library that
need to be linked into all libraries and executables. To accomplish
that, refactor the dependency handling so libprofile-extras can be added
as a 'WholeStaticLib'.
This is done by creating a new dependency type (with a coverageDepTag
dependency tag) to add libprofile-extras as a dependency for all modules
that can potentially link with coverage. During the flags() call, this
dependency is moved as a WholeStaticLib dependency iff coverage is
enabled in this link step.
There are a few NFC changes as well:
- deps() takes a DepsContext parameter.
- flags() has an extra PathDeps parameter and return value.
- add useSdk() helper to cc.Module.
Test: Build with coverage and check that we can generate coverage using
SIGUSR1 and the debug.coverage.flush sysprop.

Bison is currently looking for m4 directly in `/usr/bin/m4`, instead of
through $PATH, so it hadn't been tracked via the $PATH interposer
checks. But if you don't install m4 at all, it starts failing.

Bug: 130111713
Test: Run on a machine without m4, build passes

sanitizerRuntimeDepsMutator only modifies the currently visited
module, it can visit modules in parallel.
Also, stop recursing into modules that are not static dependencies,
and stop recursing if the module already has all modifications that
the mutator could make.

Sanitizer coverage is currently broken with the experimental pass
manager. See b/133876586 for more information. The patch is currently
being worked on upstream (https://reviews.llvm.org/D62888), but is not
ready yet. Hence, we disable it here (similar to the LTO bug).

Test: Build anything with SANITIZE_TARGET='fuzzer', verify that it has
'sancov' symbols.
