Fix C output for modern C initiative

GCC 14 on aarch64 rejects the C code written by GHC with this kind of
error:

   error: assignment to ‘ffi_arg’ {aka ‘long unsigned int’} from ‘HsPtr’ {aka ‘void *’} makes integer from pointer without a cast [-Wint-conversion]
         68 | *(ffi_arg*)resp = cret;
            |                 ^

Add the correct cast.

Prefer RdrName over OccName for looking up locations in doc renaming step

Looking up by OccName only does not take into account when functions are
only imported in a qualified way.

Fixes issue #24294

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.

Bump submodule text to 2.1.1

T17123 allocates less because of improvements to Data.Text.concat in 1a6a06a.

Bump bytestring submodule to something closer to 0.12.1

...mostly so that 16d6b7e835ffdcf9b894e79f933dd52348dedd0c
(which reworks unaligned writes in Builder) and the stuff in
https://github.com/haskell/bytestring/pull/631 can see wider testing.

The less-terrible code for unaligned writes used in Builder on
hosts not known to be ulaigned-friendly also takes less effort
for GHC to compile, resulting in a metric decrease for T21839c
on some platforms.

The metric increase on T21839r is caused by the unrelated commit
750dac33465e7b59100698a330b44de7049a345c.  It perhaps warrants
further analysis and discussion (see #23822) but is not critical.

Metric Decrease:
T21839c
Metric Increase:
T21839r

driver: Check transitive closure of haskell package dependencies when deciding whether to relink

We were previously just checking whether direct package dependencies had
been modified. This caused issues when compiling without optimisations
as we wouldn't relink the direct dependency if one of its dependenices
changed.

Fixes #23724
