[HLSL] Use hidden visibility for external linkage. (#140292) 
Implements

https://github.com/llvm/wg-hlsl/blob/main/proposals/0026-symbol-visibility.md.

The change is to stop using the `hlsl.export` attribute. Instead,
symbols with "program linkage" in HLSL will have export linkage with
default visibility, and symbols with "external linkage" in HLSL will
have export linkage with hidden visibility.
