Rephrase error message to say "visible arguments" (#24318)

* Main change: make the error message generated by mkFunTysMsg more
  accurate by changing "value arguments" to "visible arguments".

* Refactor: define a new type synonym VisArity and use it instead of
  Arity in a few places.

It might be the case that there other places in the compiler that should
talk about visible arguments rather than value arguments, but I haven't
tried to find them all, focusing only on the error message reported in
the ticket.

Introduce exception context

Here we introduce the `ExceptionContext` type and `ExceptionAnnotation`
class, allowing dynamically-typed user-defined annotations to be
attached to exceptions.

base: Introduce exception backtraces

Here we introduce the `Backtraces` type and associated machinery for
attaching these via `ExceptionContext`. These has a few compile-time
regressions (`T15703` and `T9872d`) due to the additional dependencies
in the exception machinery.

As well, there is a surprisingly large regression in the
`size_hello_artifact` test. This appears to be due to various `Integer` and
`Read` bits now being reachable at link-time. I believe it should be
possible to avoid this but I have accepted the change for now to get the
feature merged.

compiler: Don't show ExceptionContext of GhcExceptions

Most GhcExceptions are user-facing errors and therefore the
ExceptionContext has little value. Ideally we would enable
it in the DEBUG compiler but I am leaving this for future work.

rts: Fix SET_HDR initialization of retainer set

This fixes a regression in retainer set profiling introduced by
b0293f78cb6acf2540389e22bdda420d0ab874da. Prior to that commit
the heap traversal word would be initialized by `SET_HDR` using
`LDV_RECORD_CREATE`. However, the commit added a `doingLDVProfiling`
check in `LDV_RECORD_CREATE`, meaning that this initialization no longer
happened.

Given that this initialization was awkwardly indirectly anyways, I have
fixed this by explicitly initializating the heap traversal word to
`NULL` in `SET_PROF_HDR`. This is equivalent to the previous behavior,
but much more direct.

Fixes #24513.

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.

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: 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.
