  [NFC][clang] Adjust PPMemoryAllocationsTest threshold for ASan (#209024)

PPMemoryAllocationsTest.PPMacroDefinesAllocations measures the memory
footprint of the preprocessor allocator and asserts a strict threshold
of 130.0 bytes per define.

When built with ASan, the allocator adds redzones to allocations,
which increases the total memory reported by `getTotalMemory()` and
causes the test to fail (reporting ~136.8 bytes per define).

Adjust the threshold to 145.0 bytes per define when built with ASan
(detected via `LLVM_ADDRESS_SANITIZER_BUILD`) to account for this
overhead while maintaining the strict limit for standard builds.
