Properly scale default skin font according to DPI (Open-Shell#1110)

Original fix introduced in 528d15 was not correct.

started with.

We should use `SystemParametersInfoForDpi` (available since Win10 1607)
that returns properly scaled font size.

Fixes Open-Shell#1110

Setup: Recognize also /h and /help parameters (Open-Shell#1278)

Otherwise they will get passed to `msiexec` that will display its help
window that may confuse our users (as they expect our help to be displayed).

Most of settings defined in `AllSystemSettings_{253E530E-387D-4BC2-959D-E6F86122E5F2}.xml` now refer to the new font.
