Compat is not part of the Emacs code base. It is instead distributed via
GNU ELPA. It is an Elisp compatibility library, which allows packages to
use functions and macros introduced in newer versions of Emacs, while
staying backward compatible. For example, the function
`keymap-local-set' will be introduced as part of Emacs 29.1.
Correspondingly, Compat 29.1 provides this function too. A package
targeting Emacs 24.4 and newer can then depend on Compat 29.1 and use
`keymap-local-set'.

See the GNU ELPA Compat page https://elpa.gnu.org/packages/compat.html
and the manual linked there for more details.
