GHCi: Support local Prelude

Fixes #10920, an issue where GHCi bails out when started alongside a
file named Prelude.hs or Prelude.lhs (even empty file suffices).

The in-source Note [GHCi and local Preludes] documents core reasoning.

Supplementary changes:

 * add debug traces for module lookups under -ddump-if-trace;
 * drop stale comment in GHC.Iface.Load;
 * reduce noise in -v3 traces from GHC.Utils.TmpFs;
 * new test, which also exercizes HomeModError.

rts: use page sized mblocks on wasm

This patch changes mblock size to page size on wasm. It allows us to
simplify our wasi-libc fork, makes it much easier to test third party
libc allocators like emmalloc/mimalloc, as well as experimenting with
threaded RTS in wasm.

Fix a float-out error

Ticket #24768 showed that the Simplifier was accidentally destroying
a join point.  It turned out to be that we were sending a bottoming
join point to the top, accidentally abstracting over /other/ join
points.

Easily fixed.
