Build a dynamic library for Slang

- Change the `slang` project from a static library to a dynamic one

- Add some details around `slang.h` to make sure DLL export stuff is working

- Make the `slangc` executable use the dynamic library

- Rename the `glslang` sub-project to `slang-glslang` and move it into the main source hierarchy
  - This reflects the fact that it isn't a stand-alone tool, and isn't in any way a standard binary of glslang, but rather just an artifact of how Slang uses glslang
