Add gfx interface definition in Slang. (#2364)

* Add gfx interface definition in Slang.

- add gfx interface definitons in Slang.
- fix slang compiler to correctly type-check `out` interface argument.
- modify gfx interface to be fully COM compatible
- add convenient ShaderProgram creation methods to gfx.

* Fix compile errors and warnings.

* Update project files

* Fix cuda.

* Properly implement queryInterface in command encoder impls.
