Optionally skip linking/copying the built-ins

The dashed invocation of Git commands (git-rev-parse instead of git rev-parse) is deprecated for a long time already. This patch series makes it possible to skip building (and installing) them.

Incidentally, these patches also handle the .pdb issue in MSVC's install Makefile target that Peff pointed out in the context of the "slimming down" patch series
[https://lore.kernel.org/git/[email protected]/]
.

This addresses https://github.com/gitgitgadget/git/issues/406

Changes since v3:

* We now skip linking the built-ins in all CI jobs, including the containerized builds.
* The commit message of the third patch was rewritten for clarity.
* Rebased on top of master to resolve merge conflicts with jk/slimmed-down.

Changes since v2:

* Reworded and clarified the commit messages of the second and the third patch.

Changes since v1:

* Fixed check-docs under SKIP_DASHED_BUILT_INS
* Renamed ALL_PROGRAMS_AND_BUILT_INS to ALL_COMMANDS_TO_INSTALL to reflect its purpose better.
* Revamped the commit message of patch 2/3 and 3/3.
