This is a no-op but will be used in upcoming scudo changes that allow to
change the buffer size at process startup time, and as such we will no
longer be able to call __scudo_get_ring_buffer_size in debuggerd.

With this change we can report memory errors involving secondary
allocations. Update the existing crasher tests to also test
UAF/overflow/underflow on allocations with sizes sufficient to trigger
the secondary allocator.

The SYNC tagging level enables stack trace collection for allocations and
deallocations, which allows allocation and deallocation stack traces to
appear in tombstones when encountering a tag check fault in synchronous tag
checking mode.

Exports GWP-ASan allocator information callbacks to libdebuggerd so that
tombstoned can get information from the GWP-ASan allocator in the case
of a crash.

Define a "linker_bin_template" cc_defaults module that a native bridge
implementation can inherit to define a guest linker.
Break the debuggerd_init call off into separate
linker_debuggerd_{android,stub}.cpp files to allow opting in/out of the
debuggerd integration without needing to change how linker_main.cpp is
compiled. (This is necessary for a later commit that moves
linker_main.cpp into a new static library.)
