Fix genapply for cross-compilation by nuking fragile CPP logic

This commit fixes incorrectly built genapply when cross compiling
(#24347) by nuking all fragile CPP logic in it from the orbit. All
target-specific info are now read from DerivedConstants.h at runtime,
see added note for details. Also removes a legacy Makefile and adds
haskell language server support for genapply.

rts: enable wasm32 register mapping

The wasm backend didn't properly make use of all Cmm global registers
due to #24347. Now that it is fixed, this patch re-enables full
register mapping for wasm32, and we can now generate smaller & faster
wasm modules that doesn't always spill arguments onto the stack. Fixes #22460 #24152.

Fix FMA instruction on LLVM

We were emitting the wrong instructions for fused multiply-add
operations on LLVM:

  - the instruction name is "llvm.fma.f32" or "llvm.fma.f64", not "fmadd"
  - LLVM does not support other instructions such as "fmsub"; instead
    we implement these by flipping signs of some arguments
  - the instruction is an LLVM intrinsic, which requires handling it
    like a normal function call instead of a machine instruction

Fixes #24223

compiler: remove unused GHC.Linker module

The GHC.Linker module is empty and unused, other than as a hack for
the make build system. We can remove it now that make is long gone;
the note is moved to GHC.Linker.Loader instead.

base: with{Binary}File{Blocking} only annotates own exceptions

Fixes #20886

This ensures that inner, unrelated exceptions are not misleadingly
annotated with the opened file.

Fix fma warning when using llvm on aarch64.

On aarch64 fma is always on so the +fma flag doesn't exist for that
target. Hence no need to try and pass +fma to llvm.

Fixes #24379

No shadowing warnings for NoFieldSelector fields

This commit ensures we don't emit shadowing warnings when a user
shadows a field defined with NoFieldSelectors.

Fix bug wrong span of nested_doc_comment #24378

close #24378
1. Update the start position of span in `nested_doc_comment` correctly.
and hence the spans of identifiers of haddoc can be computed correctly.
2. add test `HaddockSpanIssueT24378`.

Fix irrelevant dodgy-foreign-imports warning on import f-pointers by value

A test *сс018* is attached (not sure about the naming convention though).
Note that without the fix, the test fails with the *dodgy-foreign-imports*
warning passed to stderr. The warning disappears after the fix.

GHC shouldn't warn on imports of natural function pointers from C by value
(which is feasible with CApiFFI), such as

```haskell
foreign import capi "cc018.h value f" f :: FunPtr (Int -> IO ())
```

where

```c
void (*f)(int);
```

See a related real-world use-case
[here](https://gitlab.com/daniel-casanueva/pcre-light/-/merge_requests/17).
There, GHC warns on import of C function pointer `pcre_free`.
