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.
