Add OSX LLVM JIT support (#2130)

* #include an absolute path didn't work - because paths were taken to always be relative.

* Small fixes.
Added compiler crash with generic defined in a function.
Added enum-flags test that works (by limiting backing type to int), and using __EnumType constraint.

* Add comment about crash.

* Disable crashing test.

* Fixes to make compile on OSX.

* Add github build for OSX.

* Make premake generator a utility.

* Fix osx compilation issue.

* More fixes for OSX build.

* OSX fix due to ambiguity around size_t and integer types.

* Disable xlib on build on osx.

* Use 'prebuildcommands' to make prebuild make utility projects do something.

* Small fixes for premake so utility works on linux/osx.

* Another hack to try and make generators run when 'utility'

* Fix typo in macos.yml.

* Revert premake to old style, and disable stdlib embedding on OSX.

* OSX testing.

* Fix pipe handling for OSX.

* Enable testing on OSX.

* Small fix because uname -p is not x64 on darwin.

* Use glslang from slang-binaries for OSX.

* Add slang-llvm on OSX.

* Upgrade slang-llvm.

* Update slang-llvm for OSX JIT fix.

* slang llvm 26

* Upgrade slang-llvm.

* Use slangUtil to get shared library filename.

* Use fixed slang-binaries.

* Another small fix.

* Rename linux build for clarity.
