  Remove signal-based ticker implementations
  
  Fixes issue #27073
  
  All supported platforms should work with the pthreads + nanosleep based
  ticker implementation. This avoids all the problems with using signals.
  
  In practice, all supported platforms were probably using the non-signal
  tickers already, which is probably why we do not get lots of reports
  about deadlocks and other weirdness: we were definately using functions
  that are not async signal safe in the tick handler (such as fflush to
  flussh the eventlog).
  
  Only Solaris was explicitly using the timer_create ticker impl, and even
  Solaris could probably use the pthreads one (if anyone cared: Solaris is
  no longer a Teir 3 supported platform).
  
  Plausibly the only supported platform that this will change will be AIX,
  which should now use the pthreads impl.

  No longer probe for timer_create in rts/configure
  
  It was only used by the TimerCreate.c ticker impl.

  Streamline expansions using HsExpansion (#25001)
  
  Notes added [Error Context Stack] [Typechecking by expansion: overview]
  Notes updated Note [Expanding HsDo with XXExprGhcRn] [tcApp: typechecking applications]
  
  -------------------------
  Metric Decrease:
      T9020
  -------------------------
  
  There are 2 key changes:
  
  1. `HsExpand` datatype mediates between expansions
  2. Replace `ErrCtxtM` to a simpler `HsCtxt` that does not depend on a `TidyEnv`
  
  This has some consequences detailed below:
  
  1. `HsExpand` datatype mediates between expansions
     * Simplifies the implementations of `tcExpr` to work on `XExpr`
     * Removes `VACtxt` (and its associated `VAExpansion` and `VACall`) datatype, it is subsumed by simply a `SrcSpan`.
     * Removes the function `addHeadCtxt` as it is now mearly setting a location
     * The function `tcValArgs` does its own argument number management
     * move `splitHsTypes` out of `tcApp`
     * Removes special case of tcBody from `tcLambdaMatches`
     * Removes special case of `dsExpr` for `ExpandedThingTc`
     * Renames `tcMonoExpr` -> `tcMonoLExpr`, `tcMonoExprNC` -> `tcMonoLExpr`
     * Renames `EValArg`, `EValArgQL` fields: `ea_ctxt` -> `ea_loc_span` and `eaql_ctx` -> `eaql_loc_span`
     * Remove `PopErrCtxt` from `XXExprGhcRn`
     * `fun_orig` in tcInstFun depends on the SrcSpan of the head of the application chain (similar to addArgCtxt)
       - it references the application chain head if it is user located, or
        uses the error context stack  as a fallback if it's a generated
        location
     * Make a new variant `GeneratedSrcSpan` in `SrcSpan` for HIEAst Nodes
      - Expressions wrapped around `GeneratedSrcSpan` are ignored and never added to the error context stack
      - In Explicit list expansion `fromListN` is wrapped with a `GeneratedSrcSpan` with `GeneratedSrcSpanDetails` field to store the original srcspan
  
  2. Replace `ErrCtxtM` to a simpler `HsCtxt` that does not depend on a `TidyEnv`
     * Merge `HsThingRn` to `HsCtxt`
     * Landmark Error messages are now just computed on the fly
     * Make HsExpandedRn and HsExpandedTc payload a located HsExpr GhcRn
     * `HsCtxt` are tidied and zonked at the end right before printing

  driver: recognise .dyn_o as a valid object file to link if passed on the command line.
  This allows plugins compiled with this suffix to run.
