feat(makefile): improve makefile execution and bind it to C-c C-m

Use the makefile-executor package instead of helm-make to execute make
targets. But we still rely on helm-make due to it's more efficient
available targets lookup function compared to that of makefile-executor.

Running make targets is bound to C-c C-m now which is nice and fast, and
completes via completing-read, which is currently giving a better
suggested candidates via selectrum+orderless than helm-make does.

And helm-make is still available via the old C-c h m keybinding.
