Topic: wasmtime / PR #11765 Speed up testing the C API in CI

alexcrichton opened PR #11765 from alexcrichton:faster-capi-testing to bytecodealliance:main:

• Use ninja on all platforms to avoid the overhead of make or whatever is used by default on Windows.
• Using ninja additionally enables building C/C++ objects in parallel by default.
• Enable parallelism when running tests to avoid running just a single test at a time.
• Move building of Rust examples out of ctest and into the "main build". This won't actually speed things up but avoids misattributing the first Rust test with minutes of runtime (as it's just building code).
• Use dynamic linking to speed up the linking phase of examples.
• Keep a configuration though that tests static linking.
• Also add a prtest:capi directive to enable C API tests in a PR.

alexcrichton commented on PR #11765:

Ok this should be good to go now. Timings before/after

platform	before	after
linux	11m4s	7m9s
macos	11m49s	9m42s
windows	21m19s	13m50s

Additionally the new static-linking-only test takes 3m5s so not too long.
