This patch improves the compile_flags.txt config used to power clangd
for the rts C codebase. The flags in the file are sampled & deduped
from a real stage1 build with clang-19 and vastly improves the IDE
accuracy when hacking the rts.

For maximum code coverage under the default settings,
compile_flags.txt defaults to threaded+profiled+dynamic+debug way.
This does not mean profdyn needs to be actually built in _build/stage1
for IDE to work. To activate IDE for other RTS ways, simply remove one
of the -D flags at the end of compile_flags.txt and restart clangd.

Considering trees containing untracked files as dirty is a bridge too
far. The chance of an untracked file significantly affecting measured
performanced metrics is quite small whereas not collecting measurements
is quite inconvenient for some workflows. We now ignore untracked files
in the dirtiness check.

Fixes #25471.

Basic changes:

* Change `catch` function to propagate exceptions using the
  WhileHandling mechanism.
* Introduce `catchNoPropagate`, which does the same as before, but
  passes an exception which can be rethrown.
* Introduce `rethrowIO` combinator, which rethrows an exception with a
  context and doesn't add a new backtrace.
* Introduce `tryWithContext` for a variant of `try` which can rethrow
  the exception with it's original context.
* onException is modified to rethrow the original error rather than
  creating a new callstack.
* Functions which rethrow in GHC.Internal.IO.Handle.FD,
  GHC.Internal.IO.Handle.Internals, GHC.Internal.IO.Handle.Text, and
  GHC.Internal.System.IO.Error are modified to not add a new callstack.

This commit fixes the layout of the additional information included when
displaying an exception, namely the type of the exception.

It also fixes the default handler's heading message to work well
together with the improved display message of SomeException.

This commit changes the Exception instance of SomeException to *simply*
display the underlying exception in `displayException`. The augmented
exception message that included the type and backtrace of the exception
are now only printed on a call to `displayExceptionWithInfo`.

At a surface level, existing programs should behave the same since the
`uncaughtExceptionHandler`, which is responsible for printing out uncaught
exceptions to the user, will use `displayExceptionWithInfo` by default.

However, unlike the instance's `displayException` method, the
`uncaughtExceptionHandler` can be overriden with
`setUncaughtExceptionHandler`. This makes the extra information opt-in
without fixing it the instance, which can be valuable if your program
wants to display uncaught exceptions to users in a user-facing way
(ie without backtraces).

This is what was originally agreed for CLC#231 or CLC#261 with regard to
the type of the exception information.

The call stack also becoming part of the default handler rather than the
Exception instance is an ammendment to CLC#164.

Discussion of the ammendment is part of CLC#285.

Before the exception backtraces proposal was implemented, ErrorCall
accumulated its own callstack via HasCallStack constraints, but
ExceptionContext is now accumulated automatically.

The original ErrorCall mechanism is now redundant and we get a duplicate
CallStack

Updates Cabal submodule to fix their usage of ErrorCallWithLocation to ErrorCall

When running the program with `runhaskell`/`runghc` the backtrace should
match the backtrace one would get by compiling and running the program.
But currently, an exception thrown in a program interpreted with
`runhaskell` will:

    * Not include the original exception backtrace at all
    * Include the backtrace from the internal GHCi/ghc rethrowing of the
      original exception

This commit fixes this divergence by not annotating the ghc(i) backtrace
(with NoBacktrace) and making sure that the backtrace of the original
exception is serialized across the boundary and rethrown with the
appropriate context.

Fixes #25116
