[scudo] Allow the quarantine code to be compiled out (#151064)
Add a new configuration option QuarantineDisabled that allows all of the
quarantine code to be compiled out.
Add new tests that verify that the code is removed properly.
On Android, this saves ~4000 bytes for 32 bit and ~6000 bytes for 64
bit.
On Android, I used some microbenchmarks that do malloc/free in a loop
and for allocations in the primary, the performance is about the same
for both 32 bit and 64 bit. For secondary allocations, I saw ~8% speed
up on 32 bit and ~3% on 64 bit speed up which feels like it could just
be code size improvements.
