Cherry-pick of #83128, #82399, and #82878, merged asea6ca2b5db,0c4e56174b, ande34eb3331frespectively. **Explanation**: Currently `test/CMakeLists.txt` can only set `SWIFT_LIT_ARGS` for all tests uniformly. This means that we can't have tests for Embedded Swift with a different set of `lit.py` arguments. Also, create new `check-swift-embedded-wasi` target from `test/CMakeLists.txt`, tweak `lit.cfg` to support WASI Clang resource dir, exclude unsupported tests based on `CPU=wasm32` instead of `OS=wasi`. **Scope**: Limited to Embedded Swift test suite. **Risk**: Low, due to limited scope. **Testing**: #82878 was incubated on `main` for 2 weeks, #82399 for 3 weeks with no disruption, #83128 merged this week, but enables all these tests on CI, which are consistently passing. **Issue**: rdar://156585717 **Reviewer**: @bnbarham
