QRegularExpression: rename AnchoredMatchOption to AnchorAtOffsetMatchOption

Browse Source 
The name of the option may cause confusion due to the fact
that it's not _fully_ anchoring the match, only anchoring it
at the offset passed to match() -- in other words, it's a
"left" anchoring. Deprecate the old name and introduce
a new one that should explain the situation better.

[ChangeLog][QtCore][QRegularExpression] The AnchoredMatchOption
match option has been deprecated in favor of
AnchorAtOffsetMatchOption, which should better describe
that the match is only anchored at the offset.

The match is constrained to start exactly at the offset passed to
match() in order to be successful, even if the pattern string does not
contain any metacharacter that anchors the match at that point.
Note that passing this option does not anchor the end of the match
to the end of the subject; if you want to fully anchor a regular
expression, use anchoredPattern().
