revert "checkout: introduce checkout.overlayMode config"

Browse Source 
This reverts 1495ff7da5 ("checkout: introduce checkout.overlayMode
config", 2019-01-08) and thus removes the checkout.overlayMode config
option.

The option was originally introduced to give users the option to make
the new no-overlay behaviour the default.  However users may be using
'git checkout' in scripts, even though it is porcelain.  Users setting
the option to false may actually end up accidentally breaking scripts.

With the introduction of a new subcommand that will make the behaviour
the default, the config option will not be needed anymore anyway.
Revert the commit and remove the config option, so we don't risk
breaking scripts.

will not update the skip-worktree bit in the index nor add/remove
files in the working directory to reflect the current sparse checkout
settings nor will it show the local changes.
checkout.overlayMode::
In the default overlay mode, `git checkout` never
removes files from the index or the working tree. When
setting `checkout.overlayMode` to false, files that appear in
the index and working tree, but not in <tree-ish> are removed,
to make them match <tree-ish> exactly.
