rts: Post ticky entry counts to the eventlog

We currently only post the entry counters, not the other global
counters as in my experience the former are more useful. We use the heap
profiler's census period to decide when to dump.

Also spruces up the documentation surrounding ticky-ticky a bit.

hadrian: Dump STG when ticky is enabled

This changes the "ticky" modifier to enable dumping of final STG as this
is generally needed to make sense of the ticky profiles.

hadrian: Introduce notion of flavour transformers

This extends Hadrian's notion of "flavour", as described in #18942.

hadrian: Add a viaLlvmBackend modifier

Note that this also slightly changes the semantics of these flavours as
we only use LLVM for >= stage1 builds.

hadrian: Drop redundant flavour definitions

Drop the profiled, LLVM, and ThreadSanitizer flavour definitions as
these can now be realized with flavour transformers.

[Sized Cmm] properly retain sizes.

This replaces all Word<N> = W<N># Word# and Int<N> = I<N># Int#  with
Word<N> = W<N># Word<N># and Int<N> = I<N># Int<N>#, thus providing us
with properly sized primitives in the codegenerator instead of pretending
they are all full machine words.

This came up when implementing darwinpcs for arm64.  The darwinpcs reqires
us to pack function argugments in excess of registers on the stack.  While
most procedure call standards (pcs) assume arguments are just passed in
8 byte slots; and thus the caller does not know the exact signature to make
the call, darwinpcs requires us to adhere to the prototype, and thus have
the correct sizes.  If we specify CInt in the FFI call, it should correspond
to the C int, and not just be Word sized, when it's only half the size.

This does change the expected output of T16402 but the new result is no
less correct as it eliminates the narrowing (instead of the `and` as was
previously done).

Bumps the array, bytestring, text, and binary submodules.
