Building Emacs compiles only the Lisp files that were changed since
the last build.

No such option, and there cannot be: modified Lisp files _must_ be
recompiled.
My recommendation is not to switch branches in the same worktree: it
doesn't work very well in Emacs because the rate of changes during
development is very high. Instead, use "git worktree add" to create a
separate worktree that uses the same .git directory, but tracks a
different branch. then you can just switch to a different directory
when you need to work on another branch, and the massive recompilation
is avoided.
