Summary [Win] Use SystemV ABI for JIT entrypoints in YarrJIT on Windows

clang-cl gives us the option of changing a function to use the SystemV ABI: https://clang.llvm.org/docs/AttributeReference.html#sysv-abi By using this on functions on the C++ / JIT boundaries, we can use the same codepaths for function calls and the same register mappings between Windows and Linux / Mac / BSD. Yarr JIT is a good self-contained place to try out this change. We should be able to enable a few disabled features in Yarr JIT on Windows in the process: YARR_JIT_ALL_PARENS_EXPRESSIONS YARR_JIT_REGEXP_TEST_INLINE YARR_JIT_BACKREFERENCES YARR_JIT_BACKREFERENCES_FOR_16BIT_EXPRS
