Set Qt::AA_EnableHighDpiScaling application attribute when Qt 5.14.x or
newer is used. This fixes a lot of scaling issues on HiDPI displays.
Unfortunately, this flag must be set only before QApllication object
creation, so the only one place where it can be done is main().
For some users on Windows the physicalDotsPerInch() could return values
that are smaller than the normal 96 DPI which leads to big dialog sizes
taking the entire screen.
So we need to ensure it is at least 96 DPI.
Closes#11405, #11407.
Unlike "toNativePath" which name clearly reflects the function result
"fromNativePath" has no such clear meaning.
Since this function converts path into uniform format "toUniformPath"
is better name.
macOS seems have an unique way to handle widget size, that is, it doesn't require
application to resize widgets manually, Qt will handle the resize job
automatically.
