The goal is simplifiy adding deduplication tables to `ModIface`
interface serialisation.
We identify two main points of interest that make this difficult:
1. UserData hardcodes what `Binary` instances can have deduplication
tables. Moreover, it heavily uses partial functions.
2. GHC.Iface.Binary hardcodes the deduplication tables for 'Name' and
'FastString', making it difficult to add more deduplication.
Instead of having a single `UserData` record with fields for all the
types that can have deduplication tables, we allow to provide custom
serialisers for any `Typeable`.
These are wrapped in existentials and stored in a `Map` indexed by their
respective `TypeRep`.
The `Binary` instance of the type to deduplicate still needs to
explicitly look up the decoder via `findUserDataReader` and
`findUserDataWriter`, which is no worse than the status-quo.
`Map` was chosen as microbenchmarks indicate it is the fastest for a
small number of keys (< 10).
To generalise the deduplication table serialisation mechanism, we
introduce the types `ReaderTable` and `WriterTable` which provide a
simple interface that is sufficient to implement a general purpose
deduplication mechanism for `writeBinIface` and `readBinIface`.
This allows us to provide a list of deduplication tables for
serialisation that can be extended more easily, for example for
`IfaceTyCon`, see the issue https://gitlab.haskell.org/ghc/ghc/-/issues/24540
for more motivation.
In addition to this refactoring, we split `UserData` into `ReaderUserData`
and `WriterUserData`, to avoid partial functions and reduce overall
memory usage, as we need fewer mutable variables.
Bump haddock submodule to accomodate for `UserData` split.

A `BinHandle` contains too much information for reading data.
For example, it needs to keep a `FastMutInt` and a `IORef BinData`,
when the non-mutable variants would suffice.
Additionally, this change has the benefit that anyone can immediately
tell whether the `BinHandle` is used for reading or writing.
Bump haddock submodule BinHandle split.

Note [Escaping kind in type signatures] explains how we deal
with escaping kinds in type signatures, e.g.
f :: forall r (a :: TYPE r). a
where the kind of the body is (TYPE r), but `r` is not in
scope outside the forall-type.
I had missed this subtlety in tcPatSynSig, leading to #24686.
This MR fixes it; and a similar bug in tc_top_lhs_type. (The
latter is tested by T24686a.)

Adds a MonadFix instance for tuples, permitting value recursion in the
"native" writer monad and bringing consistency with the existing
instance for transformers's WriterT (and, to a lesser extent, for Solo).

* Don't lock tvars when performing non-committal validation.
* If we encounter a locked tvar don't consider it a failure.
This means in-flight validation will only fail if committing at the
moment of validation is *guaranteed* to fail.
This prevents in-flight validation from failing spuriously if it happens in
parallel on multiple threads or parallel to thread comitting.

- closes #24191
- adds windows_skip, wasm_skip, wasm_arch, find_so, _find_so
- path_from_ghcPkg, collect_size_ghc_pkg, collect_object_size, find_non_inplace functions to testsuite
- adds on_windows and req_dynamic_ghc predicate to testsuite
The design is to not make the testsuite too smart and simply offload to
ghc-pkg for locations of object files and directories.

When a breakpoint is inlined, its context may change (e.g. tyvars in
scope). We must take this into account and not used the breakpoint tick
index as its sole identifier. Each instance of a breakpoint (even with
the same tick index) now gets a different "info" index.
We also need to distinguish modules:
- tick module: module with the break array (tick counters, status, etc.)
- info module: module having the CgBreakInfo (info at occurrence site)
