compiler: remove obsolete commented code in wasm NCG

It was just a temporary hack to workaround a bug in the relooper, that
bug has been fixed long before the wasm backend is merged.

compiler: change fallback function signature to Cmm function signature in wasm NCG

In the wasm NCG, when handling a `CLabel` of undefined function
without knowing its function signature, we used to fallback to `() ->
()` which is accepted by `wasm-ld`. This patch changes it to the
signature of Cmm functions, which equally works, but would be required
when we emit tail call instructions.

compiler: add optional tail-call support in wasm NCG

When the `-mtail-call` clang flag is passed at configure time, wasm
tail-call extension is enabled, and the wasm NCG will emit
`return_call`/`return_call_indirect` instructions to take advantage of
it and avoid the `StgRun` trampoline overhead.

Closes #22461.

The `IOError`-specific `catch` in the Prelude is long gone.

rts: Drop racy assertion

0e274c39bf836d5bb846f5fa08649c75f85326ac added an assertion in
`dirty_MUT_VAR` checking that the MUT_VAR being dirtied was clean.
However, this isn't necessarily the case since another thread may have
raced us to dirty the object.

rts/libdw: Silence uninitialized usage warnings

As noted in #22538, previously some GCC versions warned that various
locals in Libdw.c may be used uninitialized. Although this wasn't
strictly true (since they were initialized in an inline assembler block)
we fix this by providing explicit empty initializers.

Fixes #22538
