rel_eng: Update hackage docs upload scripts

This adds the upload of ghc-internal and ghc-experimental to our scripts
which upload packages to hackage.

Fix ghc-internal cabal file

The file mentioned some artifacts relating to the base library. I have
renamed these to the new ghc-internal variants.

Fix haddock source links and hyperlinked source

There were a few issues with the hackage links:

1. We were using the package id rather than the package name for the
   package links. This is fixed by now allowing the template to mention
   %pkg% or %pkgid% and substituing both appropiatly.
2. The `--haddock-base-url` flag is renamed to `--haddock-for-hackage`
   as the new base link works on a local or remote hackage server.
3. The "src" path including too much stuff, so cross-package source
   links were broken as the template was getting double expanded.

Fixes #24086

rts: add -xr option to control two step allocator reserved space size

This patch adds a -xr RTS option to control the size of virtual memory
address space reserved by the two step allocator on a 64-bit platform,
see added documentation for explanation. Closes #24498.

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

CorePrep: Rework lowering of BigNat# literals

Don't use bigNatFromWord#, because that's terrible:
 * We shouldn't have to traverse a linked list at run-time
   to build a BigNat# literal. That's just silly!
 * The static List object we have to create is much larger
   than the actual BigNat#'s contents, bloating code size.
 * We have to read the corresponding interface file,
   which causes un-tracked implicit dependencies. (#23942)

Instead, encode them into the appropriate platform-dependent
sequence of bytes, and generate code that copies these bytes
at run-time from an Addr# literal into a new ByteArray#.
A ByteArray# literal would be the correct thing to generate,
but these are not yet supported; see also #17747.

Since this lowering no longer reads the interface file for
GHC.Num.BigNat, the reasoning in Note [Depend on GHC.Num.Integer]
is obsoleted.  But the story of un-tracked built-in dependencies
remains complex, and Note [Tracking dependencies on primitives]
now exists to explain this complexity.
