Revert ExternalProject and FetchContent refactoring

Browse Source 
Refactoring of the ExternalProject and FetchContent modules moved
the commands into CMake scripts. This broke custom commands that
used shell redirection or special build tool variables of the form
$(MakeVar). Undo the sequence of commits that performed this
refactoring and follow-up fixes associated with it.

The following commits are reverted by this change:

4f3d1abbb4 (ExternalProject: Refactor pre-configure steps to support
no-target uses, 2021-02-05)

17e5516e60 (FetchContent: Invoke steps directly and avoid a separate
sub-build, 2021-01-29)

bd876f3849 (FetchContent: Restore patch command support,
2021-02-18)

404cddb7bb (ExternalProject: Fix misuse of IS_NEWER_THAN in
timestamp checks, 2021-02-21)

b0da671243 (FetchContent: Don't update timestamps if files don't
change, 2021-02-18)

Fixes: #21892

* Ninja generators now transform the ``DEPFILE`` generated by an
:command:`add_custom_command`. See policy :policy:`CMP0116` for details.
* The implementation of the :module:`ExternalProject` module was
significantly refactored. The patch step gained support for
using the terminal with a new ``USES_TERMINAL_PATCH`` keyword
as a by-product of that work.
* The :module:`FetchContent` module no longer creates a separate
sub-build to implement the content population. It now invokes
the step scripts directly from within the main project's
configure stage. This significantly speeds up the configure
phase when the required content is already populated and
up-to-date.
* The precompiled Linux binaries provided on
`cmake.org <https://cmake.org/download/>`_ have changed their naming pattern
to ``cmake-$ver-linux-$arch``, where ``$arch`` is either ``x86_64`` or
