  Reland '[hwasan] Add fixed_shadow_base flag (#73980)' (#95445)

This was reverted in https://github.com/llvm/llvm-project/pull/95435
because it broke Android static hwasan binaries. This reland limits the
change to !SANITIZER_ANDROID.

Original commit message:
When set to non-zero, the HWASan runtime will map the shadow base at the
specified constant address.

This is particularly useful in conjunction with the existing compiler
option 'hwasan-mapping-offset', which bakes a hardcoded constant address
into the instrumentation.
