Bump MicroCOM, add workaround for WinRT bug

[kekekeks]

WinRT has broken reference counting for effects returned from GetSource. It will Release returned ref
and attempt to use it afterward:

^^^ Use-after-free

This usually works because the wrapper effect DOES hold a reference to the COM object, so invalid memory access succeeds. In our case MicroCOM will rightfully release native memory once the latest native reference is gone.

So we need to keep CCWs alive for the entire call as a workaround.

This PR bumps MicroCOM to 0.11.4 and adds some .props that allow referencing it directly from source.
