DXC build: disable sized allocations
Chromium will enable this flag by default, which results in ASAN
failures for mismatched new/delete calls in DXC. These are not a
security risk, and haven't been fixed in upstream LLVM either, so let's
disable this flag when building DXC. Note that this is already disabled
for MSVC builds as well (both in our GN build, and in DXC's CMake
build).
