rts: expose HeapAlloc.h as public header

This commit exposes HeapAlloc.h as a public header. The intention is
to expose HEAP_ALLOCED/HEAP_ALLOCED_GC, so they can be used in
assertions in other public headers, and they may also be useful for
user code.

rts: assert pointer is indeed heap allocated in Bdescr()

This commit adds an assertion to Bdescr() to assert the pointer is
indeed heap allocated. This is useful to rule out RTS bugs that
attempt to access non-existent block descriptor of a static closure, #24492
being one such example.

ghc-experimental: Add dummy dependencies to work around #23942

This is a temporary measure to improve CI reliability until a proper
solution is developed.

Works around #23942.

Three compile perf improvements with deep nesting

These were changes are all triggered by #24471.

1. Make GHC.Core.Opt.SetLevels.lvlMFE behave better when there are
   many free variables.  See Note [Large free-variable sets].

2. Make GHC.Core.Opt.Arity.floatIn a bit lazier in its Cost argument.
   This benefits the common case where the ArityType turns out to
   be nullary. See Note [Care with nested expressions]

3. Make GHC.CoreToStg.Prep.cpeArg behave for deeply-nested
   expressions.  See Note [Eta expansion of arguments in CorePrep]
   wrinkle (EA2).

Compile times go down by up to 4.5%, and much more in artificial
cases. (Geo mean of compiler/perf changes is -0.4%.)

Metric Decrease:
    CoOpt_Read
    T10421
    T12425

Use "module" instead of "library" when applicable in base haddocks
