Artem Chernyshev 02b3719df9 feat: skip filesystem for state and ephemeral partitions in the installer
Filesystem creation step is moved on the later stage: when Talos mounts
the partition for the first time.
Now it checks if the partition doesn't have any filesystem and formats
it right before mounting.

Additionally refactored mount options a bit:
- replaced separate options with a set of binary flags.
- implemented pre-mount and post-unmount hooks.

And fixed typos in couple of places and increased timeout for `apid ready`.
