Interpreter: Add locking for communication with external interpreter

This adds locking to communication with the external interpreter
to prevent concurrent tasks interfering with each other. This
fixes Template Haskell with the external interpreter in parallel (-j)
builds.

Fixes #25083

Use monospace font for "Either a b" in fmap docs

The documentation for fmap shows "`Either a b`" in the default font
instead of showing "Either a b" in a monospace font.

Parser: remove non-ASCII characters from Parser.y

Non-ASCII characters in the source causes a problem with the default
Haskell Language Server setup in VSCode. Two characters seems to have
been left in by accident.

Workaround for #25396

wasm: bump dyld v8 heap size limit

This patch adds `--max-old-space-size=8192` to wasm dyld shebang
arguments to bump V8 heap size limit. The default limit
(`heap_size_limit` returned by `v8.getHeapStatistics()`) is
dynamically determined and a bit too low under certain workloads, and
V8 would waste too much CPU time to garbage collect old generation
heap more aggressively. Bumping the limit to 8G doesn't imply dyld
would really take that much memory at run-time, but it lessens V8 heap
stress significantly.

Add requestTickyCounterSamples to GHC.Internal.Profiling

This allows the user to request ticky counters to be written to
the eventlog at specific times.

See #24645

Move defaulting code into a new module

GHC.Tc.Solver had reached 4,000 lines -- although quite a lot of them
are comments.

This MR

* Adds the new module GHC.Tc.Solver.Default, which has all the
  complex, but well modularised, defaulting code

* Moves a bit of code from GHC.Tc.Solver into the existing
  GHC.Tc.Solver.Solve. Notably solveWanteds and simplifyWantedsTcM,
  which are called from GHC.Tc.Solver.Default

It's a pure refactor.  No code changes.

Improve the generalisation code in Solver.simplifyInfer

The code in `decideQuantification` has become quite complicated.
This MR straightens it out, adds a new Note, and on the way
fixes #25266.

See especially Note [decideAndPromoteTyVars] which is is where
all the action happens in this MR.

Adjust catches to properly rethrow exceptions

https://gitlab.haskell.org/ghc/ghc/-/merge_requests/13302 implemented exception
rethrowing proposal, but it didn't adjust `catches`. This fixes it.
