This reapplies 8fa66c6ca7 ([asan][windows]
Eliminate the static asan runtime on windows) for a second time.
That PR bounced off the tests because it caused failures in the other
sanitizer runtimes, these have been fixed by only building interception,
sanitizer_common, and asan with /MD, and continuing to build the rest of
the runtimes with /MT. This does mean that any usage of the static
ubsan/fuzzer/etc runtimes will mean you're mixing different runtime
library linkages in the same app, the interception, sanitizer_common,
and asan runtimes are designed for this, however it does result in some
linker warnings.
Additionally, it turns out when building in release-mode with
LLVM_ENABLE_PDBs the build system forced /OPT:ICF. This totally breaks
asan's "new" method of doing "weak" functions on windows, and so
/OPT:NOICF was explicitly added to asan's link flags.
