added option to scale tooltip rendering

[NorthFury]

The old rendering is unchanged in function, despite the heavy refactoring.
Some existing tooltip rendering issues are fixed now, for example, the bold character is no longer considered when computing the tooltip width.
I removed DEC_INTERNAL_LEADING since WinFont is not supposed to be used except for the Chinese build. It also fixes the font alignment if it is enabled for other builds.

The fast help text is parsed multiple times. This resulted in some duplication of a good chunk of code. Doing this cleanly would mean to parse it when updating FastHelpText. The parsing result would be a <list<list<WeightedText>> that would be saved besides FastHelpText. This represents a list of lines. Each line would have parts of text that is continuously bold or regular font. WeightedText would be a struct with bool isBold and STR16 text properties.

Known Issue:

• The bold and the regular font rendering doesn't align properly in regards to height. Rounding is done when selecting the font and I think this results in this inconsistent height alignment. A potential solution may be to provide fixed scaling factors with predefined LOGFONT settings. The issue itself is not large as we are speaking of 1-3 pixels misalignment.

Please, next time try to separate the meaty changes, whitespace changes (not the newline additions, that's the .editorconfig file's doing, not you) and dead code removal into their own commits, it makes reviewing the PR much easier.

If the actual code changes can themselves be split up into smaller logical commits, even better.

I tested English and German and it works fine, but Chinese tooltips are broken with TOOLTIP_SCALE_FACTOR > 100

I'm only formatting the parts of the code that I'm touching and in the case of changing most of the function code, I might format the full function.
I should have mentioned that most functions in the mousesystem.cpp file were written from scratch and it's best to review it function by function instead of line by line.
I will try to be more mindful of the review process for the next changes.

I didn't try it out with the Chinese build. I hope that changing the build target will suffice to be able to test it on my side.

You'll need a Chinese gamedir as well. It's the same process as running English 1.13, with the extra step of extracting https://github.com/1dot13/gamedir-languages/tree/master/Chinese_Version on top of it.

cool, Chinese works now. thanks!
