base: Use strerror_r instead of strerror

As noted by #24344, `strerror` is not necessarily thread-safe.
Thankfully, POSIX.1-2001 has long offered `strerror_r`, which is
safe to use.

Fixes #24344.

forall in a type with -XNoExplicitForAll used to suggest RankNTypes.
In this patch this is changed to the correct ExplicitForAll.

using a where in a data declaration with -XNoGADTSyntax used to suggest GADTs
In this patch this is changed to the correct GADTSyntax.

Error messages: Improve Error messages for Data constructors in type signatures.

This patch improves the error messages from invalid type signatures by
trying to guess what the user did and suggesting an appropriate fix.

Partially fixes: #17879

HieAst: add module name #24493

The main purpose of this is to tuck the module name `xxx` in `module xxx where` into the hieAst.
It should fix #24493.

The following have been done:
1. Renamed and update the `tcg_doc_hdr :: Maybe (LHsDoc GhcRn)` to `tcg_hdr_info :: (Maybe (LHsDoc GhcRn), Maybe (XRec GhcRn ModuleName))`
   To store the located module name information.
2. update the `RenamedSource` and `RenamedStuff` with extra `Maybe (XRec GhcRn ModuleName)` located module name information.
3. add test `testsuite/tests/hiefile/should_compile/T24493.hs` to ensure the module name is added and update several relevent tests.
4. accompanied submodule haddoc test update MR in https://gitlab.haskell.org/ghc/haddock/-/merge_requests/53
