Refactor Libffi and RTS rules

This removes a hack that copies libffi files to the rts
build directory. This was done in a libffi rule, but now
an rts rule correctly needs and copies the relevant
files from the libffi build dir to the rts build dir.

Issues: #16272 #16304

RTS: Fix restrictive cast

Commit e75a9afd2989e0460f9b49fa07c1667299d93ee9 added an `unsigned` cast
to account for OSes that have signed `rlim_t` signed. Unfortunately,
the `unsigned` cast has the unintended effect of narrowing `rlim_t` to
only 4 bytes. This leads to some spurious out of memory crashes
(in particular: Haddock crashes with OOM whenn building docs of
`ghc`-the-library).

In this case, `W_` is a better type to cast to: we know it will be
unsigned too and it has the same type as `*len` (so we don't suffer from
accidental narrowing).

Hadrian: add --test-root-dirs, to only run specific directories of tests

We can specify several of those, by using the flag multiple times or
just once but combining the directories with ':'.

Along the way, this patch also fixes the testsuite-related --only flag,
so that we can use it many times instead of being force to specify a
space-separated list of test in a single --only flag.

Some forall-related cleanup in deriving code

* Tweak the parser to allow `deriving` clauses to mention explicit
  `forall`s or kind signatures without gratuitous parentheses.
  (This fixes #14332 as a consequence.)
* Allow Haddock comments on `deriving` clauses with explicit
  `forall`s. This requires corresponding changes in Haddock.

Lowercase windows imports

While windows and macOS are currently on case-insensitive file
systems, this poses no issue on those.  When cross compiling from
linux with a case sensitive file system and mingw providing only
lowercase headers, this in fact produces an issue.  As such we just
lowercase the import headers, which should still work fine on a
case insensitive file system and also enable mingw's headers to
be usable porperly.
