Remove all jemalloc-related content

This commit removes all jemalloc related submodules, configuration, etc,
from the bootstrap, from the standard library, and from the compiler.
This will be followed up with a change to use jemalloc specifically as
part of rustc on blessed platforms.

-// Always use alloc_system during stage0 since we don't know if the alloc_*
-// crate the stage0 compiler will pick by default is enabled (e.g.
-// if the user has disabled jemalloc in `./configure`).
-// `force_alloc_system` is *only* intended as a workaround for local rebuilds
-// with a rustc without jemalloc.
-// FIXME(#44236) shouldn't need MSVC logic
