testsuite: Move no_lint to the top level, tweak hie002

- We don't want to benchmark linting so disable lints in hie002 perf
  test

- Move no_lint to the top-level to be able to use it in tests other than
  those in `testsuite/tests/perf/compiler`.

- Filter out -dstg-lint in no_lint.

- hie002 allocation numbers on 32-bit are unstable, so skip it on 32-bit

Metric Decrease:
    hie002

Testsuite: mark T11531 fragile

The test depends on a link editor allowing undefined symbols in an ELF
shared object. This is the standard but it seems some distributions
patch their link editor. See the report by @hsyl20 in #11531.

Fixes #11531

Significant refactor of Lint

This refactoring of Lint was triggered by #17923, which is
fixed by this patch.

The main change is this.  Instead of
   lintType :: Type -> LintM LintedKind
we now have
   lintType :: Type -> LintM LintedType

Previously, all of typeKind was effectively duplicate in lintType.
Moreover, since we have an ambient substitution, we still had to
apply the substition here and there, sometimes more than once. It
was all very tricky, in the end, and made my head hurt.

Now, lintType returns a fully linted type, with all substitutions
performed on it.  This is much simpler.

The same thing is needed for Coercions.  Instead of
  lintCoercion :: OutCoercion
               -> LintM (LintedKind, LintedKind,
                         LintedType, LintedType, Role)
we now have
  lintCoercion :: Coercion -> LintM LintedCoercion

Much simpler!  The code is shorter and less bug-prone.

There are a lot of knock on effects.  But life is now better.

Use conLikeUserTyVarBinders to quantify field selector types

This patch:

1. Writes up a specification for how the types of top-level field
   selectors should be determined in a new section of the GHC User's
   Guide, and
2. Makes GHC actually implement that specification by using
   `conLikeUserTyVarBinders` in `mkOneRecordSelector` to preserve the
   order and specificity of type variables written by the user.

Fixes #18023.

hadrian: Don't --export-dynamic on Darwin

When fixing #17962 I neglected to consider that --export-dynamic is only
supported on ELF platforms.

Add an INLINE pragma to Control.Category.>>>

This fixes #18013 by adding INLINE pragmas to both Control.Category.>>>
and GHC.Desugar.>>>. The functional change in this patch is tiny (just
two lines of pragmas!), but an accompanying Note explains in gory
detail what’s going on.
