[scudo][standalone] Compact pointers for Caches/Batches

This CL introduces configuration options to allow pointers to be
compacted in the thread-specific caches and transfer batches. This
offers the possibility to have them use 32-bit of space instead of
64-bit for the 64-bit Primary, thus cutting the size of the caches
and batches by nearly half (and as such the memory used in size
class 0). The cost is an additional read from the region information
in the fast path.

This is not a new idea, as it's being used in the sanitizer_common
64-bit primary. The difference here is that it is configurable via
the allocator config, with the possibility of not compacting at all.

This CL enables compacting pointers in the Android and Fuchsia default

Rewrite MSVC toolchain discovery with VFS

This fixes an issue where the toolchain discovery doesn't respect the
VFS's current working directory, specifically clangd not respecting a
relative /winsysroot.
