Ivan Lozano 4a363734b3 Add integer_overflow sanitization build option.
Adds the SANITIZE_TARGET=integer_overflow build option to apply signed and
unsigned integer overflow sanitization globally. This implements the
Make side of the build option.

A LOCAL_SANITIZE_BLACKLIST variable is added to allow blacklists to be
defined in make files, mirroring similar functionality provided in Soong.

An additional build option is provided to control whether or not to run
in diagnostics mode, controlled by SANITIZE_TARGET_DIAG. This works the
same way that SANITIZE_TARGET does and currently only supports
'integer_overflow' as an option.

Bug: 30969751
Test: Building with and without the new flags, device boot-up, tested
various permutations of controlling the new flags from build files.
