Use ParserFlags in GHC.Runtime.Eval (#17957)

Instead of passing `DynFlags` to functions such as `isStmt` and
`hasImport` in `GHC.Runtime.Eval` we pass `ParserFlags`. It's a much
simpler structure that can be created purely with `mkParserFlags'`.

GHC.Runtime: avoid DynFlags (#17957)

* remove unused `DynFlags` parameter from `emptyPLS`

Avoid DynFlags in Ppr code (#17957)

* replace `DynFlags` parameters with `SDocContext` parameters for a few
  Ppr related functions: `bufLeftRenderSDoc`, `printSDoc`,
  `printSDocLn`, `showSDocOneLine`.

* remove the use of `pprCols :: DynFlags -> Int` in Outputable. We
  already have the information via `sdocLineLength :: SDocContext ->
  Int`

Avoid using sdocWithDynFlags (#17957)

Remove one use of `sdocWithDynFlags` from `GHC.CmmToLlvm.llvmCodeGen'`
and from `GHC.Driver.CodeOutput.profilingInitCode`

Avoid `sdocWithDynFlags` in `pprCLbl` (#17957)

* add a `DynFlags` parameter to `pprCLbl`
* put `maybe_underscore` and `pprAsmCLbl` in a `where` clause to avoid
  `DynFlags` parameters

CmmToAsm DynFlags refactoring (#17957)

* Remove `DynFlags` parameter from `isDynLinkName`: `isDynLinkName` used
  to test the global `ExternalDynamicRefs` flag. Now we test it outside of
  `isDynLinkName`

* Add new fields into `NCGConfig`: current unit id, sse/bmi versions,
  externalDynamicRefs, etc.

* Replace many uses of `DynFlags` by `NCGConfig`

* Moved `BMI/SSE` datatypes into `GHC.Platform`

Trees That Grow refactor for `ConPat` and `CoPat`

- `ConPat{In,Out}` -> `ConPat`

- `CoPat` -> `XPat (CoPat ..)`

Note that `GHC.HS.*` still uses `HsWrap`, but only when `p ~ GhcTc`.
After this change, moving the type family instances out of `GHC.HS.*` is
sufficient to break the cycle.

Add XCollectPat class to decide how binders are collected from XXPat based on the pass.

Previously we did this with IsPass, but that doesn't work for Haddock's
DocNameI, and the constraint doesn't express what actual distinction is being
made. Perhaps a class for collecting binders more generally is in order, but we
haven't attempted this yet.

Pure refactor of code around ConPat

 - InPat/OutPat synonyms removed

 - rename several identifiers

 - redundant constraints removed

 - move extension field in ConPat to be first

 - make ConPat use record syntax more consistently

Fix T6145 (ConPatIn became ConPat)

Add comments from SPJ.

Add comment about haddock's use of CollectPass.

Updates haddock submodule.
