Lower the priority of normal keymap and remove some shims

[DogLooksGood]

All keymap in meow had the high priority by setting emulation-mode-map-alists. In normal state, the result is every minor mode single key commands are covered by normal mode commands. We added a lot shims to work out of this, however it doesn't seems to be necessary to me.

By lowering the keymap's priority, we can get rid of some shims, e.g. edebug, company, corfu, magit-blame, etc. They just work now.

Just tested this PR with package-vc-install (and recompiling and restarting just to be safe) and my motion keys just executed self-insert-command instead of navigation commands with grep-edit. So #656 is still valid (just how the wgrep shim still is I'd guess, since you didn't remove it in this commit).

I want to have a automatic normal/motion switching by detecting if there's an self-insert-command bound to single keys. there may be some tricky edge cases, I'll give it a try.
