Controller preferences: add :hwbtn: markup parser

[ronso0]

Allows using :hwbtn:LABEL in xml and moves the styling to c++

It's just bold now (dropped the tt monospace font tag).

The only way I figured to get horizontal padding was to wrap the label in  
_{Padding is not applied with padding: 2px; alone. Might be one of those qss quirks where we need to set an unrelated property, though with span neither display: inline-block; nor box-sizing: border-box; or border work}

@acolombier Mind taking a look?

It works, but only for block elements or table cells. Unfortunately, using table cells also introduces a linebreak, so we can't use it here:

Thanks for looking into it @Holzhaus

I think we're good with the   solution. I expect it to look odd only if users have a monospace font configured e.g. with Qt6ct.

oh, you already have fix ...

No, just some minor improvement unfortunately 😢

LGTM in terms of code. Can't comment much on the formatting because I don't know HTML&CSS well enough.
