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.

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

rts: Drop .wasm suffix from .prof file names
This replicates the behavior on Windows, where `Hi.exe` will produce
profiling output named `Hi.prof` instead of `Hi.exe.prof`.
While in the area I also fixed the extension-stripping logic, which
incorrectly rewrote `Hi.exefoo` to `Hi.foo`.
Closes #24515.

rts/linker: Enable GOT support on all platforms
There is nothing platform-dependent about our GOT implementation and
GOT support is needed by `T24171` on i386.

rts: Lazily decode IPE tables
Previously we would eagerly allocate `InfoTableEnt`s for each
info table registered in the info table provenance map. However, this
costs considerable memory and initialization time. Instead we now
lazily decode these tables. This allows us to use one-third the memory
*and* opens the door to taking advantage of sharing opportunities within
a module.
This required considerable reworking since lookupIPE now must be passed
its result buffer.

CorePrep: Rework lowering of BigNat# literals
Don't use bigNatFromWord#, because that's terrible:
* We shouldn't have to traverse a linked list at run-time
to build a BigNat# literal. That's just silly!
* The static List object we have to create is much larger
than the actual BigNat#'s contents, bloating code size.
* We have to read the corresponding interface file,
which causes un-tracked implicit dependencies. (#23942)
Instead, encode them into the appropriate platform-dependent
sequence of bytes, and generate code that copies these bytes
at run-time from an Addr# literal into a new ByteArray#.
A ByteArray# literal would be the correct thing to generate,
but these are not yet supported; see also #17747.
Since this lowering no longer reads the interface file for
GHC.Num.BigNat, the reasoning in Note [Depend on GHC.Num.Integer]
is obsoleted. But the story of un-tracked built-in dependencies
remains complex, and Note [Tracking dependencies on primitives]
now exists to explain this complexity.
Additionally, many empty imports have been modified to refer to
this new note and comply with its guidance. Several empty imports
necessary for other reasons have also been given brief explanations.
