Add ZonkAny and document it

This MR fixed #24817 by adding ZonkAny, which takes a Nat
argument.

See Note [Any types] in GHC.Builtin.Types, especially
wrinkle (Any4).

hadrian: Make sure ffi headers are built before using a compiler

When we are using ffi adjustors then we rely on `ffi.h` and
`ffitarget.h` files during code generation when compiling stubs.

Therefore we need to add this dependency to the build system (which this
patch does).

Reproducer, configure with `--enable-libffi-adjustors` and then build
"_build/stage1/libraries/ghc-prim/build/GHC/Types.p_o".

Observe that this fails before this patch and works afterwards.

Fixes #24864

base: Deprecate BCO primops exports from GHC.Exts

See https://github.com/haskell/core-libraries-committee/issues/212.

These reexports will be removed in GHC 9.14.

Adjust test timings for slower computers

Increase the delays a bit to be able to run these tests on slower
computers.

The reference was a Lichee Pi 4a RISCV64 machine.

RISCV64: Ignore divbyzero test

The architecture's behaviour differs from the test's expectations. See
comment in code why this is okay.

RISCV64: Add additional linker symbols for builtins

We're relying on some GCC/Clang builtins. These need to be visible to
the linker (and not be stripped away.)

it.

Add test for C calling convention

Ensure that parameters and return values are correctly processed. A
dedicated test (like this) helps to get the subtleties of calling
conventions easily right.

The test is failing for WASM32 and marked as fragile to not forget to
investigate this (#25249).

linker: add --optimistic-linking flag

This patch adds:

- the --optimistic-linking flag which binds unknown symbols in the
runtime linker to 0xDEADBEEF instead of exiting with failure

- The test T25240 which tests these flags using dead code in the FFI system.

- closes #25240

This patch is part of the upstreaming haskell.nix patches project.
