QPlatformTheme::removeMnemonics() removes any match to /\s*\(&[^&]\)/
from the text it is given (a menu entry). It transpires that
translators are apt to use the full-width parentheses (compatible with
some far-eastern scripts) instead of the plain ASCII ones. This leads
to their translated mnemonics don't match the same pattern unless we
treat the full-width parentheses as a match for the ASCII ones;
consequently, they don't get removed, which this function exists to
do. So teach it to recognize the full-width versions, too.
In the process, break out the pattern-matching (aside from the leading
space) to a lambda to make it easier to read and document.
