Move Label component out of Input folder and let it accept for Typography "types"

[git-toni]

It seems Label can be used not only for Input-based types but also for other cases such as Select. I suggest to:

• Move Label to its own folder.
• Let Label accept different type props, so the Typography color it is using is more flexible. Currently it can only be either secondary or primary, which is not enough for Select for example.

Make sure these boxes are ticked before submitting a new issue:

• I have checked that this is not a duplicate
• I have added a label categorizing this under BLKN | Kiwicom | Icons | Global

I didn't specify form inputs yet, but it'll be done in next days, but... Are we sure we need own component for this? If it's only because of visual look, we will solve visual consistency (and easy updating) with use of design tokens.

@darkwindcz Can I close it ? <FormLabel /> is available since #219
