Fix docstring.

While `major-mode-remap-alist` provides a way for users to indicate the
major mode of their choice, we need a similar variable for the
use of packages.

This patch adds a new `major-mode-remap-defaults` and changes various
packages to obey it or make use of it.
I think it nicely cleans the regexp duplication between CC-mode and
`c-ts-mode.el` and also makes it easier/cleaner for users to override
the changes made by `*-ts-mode.el`.
