Ruby 1.49.0.pre1 - grpc getting gRPC dynamic C core load error on x64-mingw-ucrt

[johnnyshields]

@apolcyn I've found a critical issue with grpc Ruby 1.49.0.pre1 on a clean install of Windows / Ruby 3.1 x64-mingw-ucrt. The symptom is the error Couldn't find or load gRPC's dynamic C core (LoadError) when loading the gem.

I've found that renaming grpc_c.64-ucrt.ruby to grpc_c.64-msvcrt.ruby fixes the issue. Note that the -ucrt gem comes with the following binaries (msvcrt are empty):

grpc_c.32-msvcrt.ruby - 0 KB
grpc_c.64-msvcrt.ruby - 0 KB
grpc_c.64-ucrt.ruby - 9,650 KB

(This means that in the builds I've made so far, it's actually been loading the msvcrt binary on ucrt the whole time. Oops 🤦‍♂️)

It would be ideal to fix this before the full release of 1.49.0.
