Inline global constants for shader style CPU targets (#8686)

On the shader-host-callable target, test `gh-4874.slang` generates IR
that contains global constants referencing global params. These need to
get inlined into functions, as otherwise
`introduceExplicitGlobalContext()` will fail with "no outer func at use
site for global", making the test crash the compiler.
