Rename Qt::Key_mu to Qt::Key_micro

The old name misleadingly identifies it as the Greek letter on which
it is based (and to which it case-folds); but U+00B5 is MICRO SIGN,
not the Greek letter mu, and pretending it is the latter only leads to
confusion.

Retain the old name as an alias to the new, prepare to deprecate it
from 6.11 and change all uses of it to the new name.

[ChangeLog][QtCore][Qt::Key] Qt::Key_mu is now renamed Key_micro,
since it is, in fact, the micro sign, not the Greek letter mu. The old
name is retained as an alias for the time being.
