macos: normalize Composed("p") -> Char('p') when use_ime=true

Browse Source 
When the IME is enabled, pressing `CTRL-A P` would generate
`Composed("P")` for the second key press, which we couldn't
then match in the keymapping layer.

This commit checks for that and normalizes it to `Char('P')`
instead.
