[asan][test][win] Remove `REQUIRES: asan-rtl-heap-interception`

[alvinhochun]

Summary

This appears to be a leftover from when these tests were first added in
D62927. Because of this, these tests had never run with check-asan or
check-asan-dynamic.

I've tested locally that these tests do pass on both i686 MSVC and MinGW
targets. They are disabled for 64-bit though, and I believe no LLVM
buildbots are testing for 32-bit Windows targets.
