  [CIR] Force emission of static local enclosing functions (#201941)

When getOrCreateStaticVarDecl is called, we need to call
`getAddressOfGlobal` to trigger the emission of the enclosing function.
In most cases this has already happened, but there are cases where the
enclosing function would not otherwise have been emitted. See
https://bugs.llvm.org/show_bug.cgi?id=18020 for details.

It appears that this was mistakenly seen as OpenMP-specific behavior
because of an OpenMP RAII guard that surrounds it in classic codegen,
but that actually is there to skip the behavior when generating OpenMP
device code.

We also needed to insert the static local decl into CIRGenModule's map
by calling `setStaticLocalDeclAddress`. To avoid a duplicate emission.
