Ivan Lozano c2d7db1c7d Overflow sanitization in frameworks/ and system/. 
Enables signed and unsigned integer overflow sanitization on-by-default
for modules in frameworks/ and system/ by using the integer_overflow
sanitization setting. This applies sanitization to dynamically linked
binaries and shared libraries, and comes with a default set of regex for
functions to exclude from sanitization.
(see build/soong/cc/config/integer_overflow_blacklist.txt)

Prepare to enable minimal runtime diagnostics for integer overflow
sanitization on userdebug and eng builds.

Adds an additional Make and product variable pair to apply integer
overflow sanitization by default to additional code paths.

Bug: 30969751
Bug: 63927620

Test: Included paths are being sanitized.

Test: CTS test suite run on Pixel, runtime errors resolved.
Test: Performance impact in benchmarks acceptable.
Test: Boot-up successful on current Google devices.
Test: Teamfooded in diagnostics mode on Pixel for a month.

Test: Phone calls, camera photos + videos, bluetooth pairing.
Test: Wifi, work profiles, streaming videos, app installation.
Test: Split-screen, airplane mode, battery saver.
Test: Toggling accessibility settings.
