Fix requirements on T25240

T25240 doesn't need RTS linker, GHCi is sufficient and GHCi can also be
dynamically linked.

TH: Add typed variants of dataToExpQ and liftData

This commit introduces to template-haskell (via ghc-internal) two
functions `dataToCodeQ` and `liftDataTyped`, typed variants of
`dataToExpQ` and `liftData` respectively.

Tested in: `dataToCodeQUnit`.

JS: Basic cleanup for unused stuff to simplify things.

1. Make `staticInitStat`, `staticDeclStat`, `allocUnboxedConStatic`, `allocateStaticList`, `jsStaticArg` local to modules.
2. Remove unused `hdRawStr`, `hdStrStr` from Haskell and JavaScript (`h$pstr`, `h$rstr`, `h$str`).
3. Introduce a special type `StaticAppKind` enumeration and `StaticApp` to represent boxed scalar static applications. Originally, StaticThunk supported to pass Maybe when it became Nothing for initializied thunks in an alternatie way but it is not used anymore.

JS: Add trivial optimizations for `unpackCString` and `unpackCStringUtf8`.

It became possible due of introduction strings unfloating at Sinker pass (#13185). Earns few more bytes at optimizations.

JS: Specialize unpackCString# CAFs (fixes #24744)

Code analysis shown that such optimization would be possible out of the box if `cachedIdentForId` allowed to do that for Haskell `Id`s which are represented by few JavaScript `Ident`s. It is a usual for strings which are represented at JavaScript as a pair of 2 values: the string content and the offset where to start reading actual string from the full content. Usually offset is 0 but technically we need to allow such complex structures to be treated as "global".

Enabling it there shown that `genToplevelRhs` and `globalOccs` had inaccuracies in their implementations:
1. `globalOccs` operated over JavaScript's `Ident`s but for complex structures it didn't pay attention to the fact that different Idents actually could be pointed to same Id. Now the algo is changed to calculate occurencies for Ids.
2. `genToplevelRhs` didn't assume that different Idents pointed to same Id can have mixed order of occurence. But actually the order is important. Strings are encoded into 2 variables where first is content and second is offset and their order are not interchangeable. It is fixed by regeneration Idents from collected Ids which is fine because all Idents generation is passed through the Cache and they are quasi-stable.

gitlab-ci: Allow use of newer cabal-install bindists

Newer cabal-install bindists have internal directory structure.
Here we detect and account for the presence of such structure.

configure: Implement ld override whitelist

Bring `configure` into alignment with `ghc-toolchain`, ensuring that the
ld-override logic will only take effect on Linux and Windows.

Fixes #25501.

gitlab-ci: Prefer system toolchain on FreeBSD

It's not uncommon to find machines with gcc installed via ports. We
should be using the system's default clang-based toolchain instead.

testsuite: Mark T16180 as "broken" on FreeBSD

Sadly we in fact need to skip it as it merely times out during
compilation.

See #14012.

testsuite: Skip T16992 unless in slow speed

This test has extraordinary memory requirements and tests a rather
niche aspect of the compact region mechanism. It has been suggested
multiple times that we shouldn't run it in the default testsuite
configuration. Finally implement this.

See #21890.
See #21892.

gitlab/ci: Don't clobber RUNTEST_ARGS

Previously the logic handling `IGNORE_PERF_FAILURES` clobbered the
user's `RUNTEST_ARGS`. Fix this.

Revert mapMG renaming

We had previously renamed this function for consistency, but that caused unnecessary breakage
