Enable use of pre-built glslang binaries (#1120)

* Enable use of pre-built glslang binaries

This change uses an updated version of the `slang-binaries` submodule that includes pre-built versions of `slang-glslang.dll` and `libslang-glslang.so`, and enables the build of the main Slang project to rely on these binaries instead of building them from source.

An option to the premake build file can be used to generate the appropriate project files for `slang-glslang`, which should enable us to build updated binaries as needed. The default option is to *not* build those projects, so that we can reduce build times in the common case (and on CI).

* fixup: different copy commands per platform

* fixup

* fixup

* fixup: remove stray line added to premake file by accident
