LazUtils Changes
Masks unit
The masks unit has been completely rewritten.
Reasons:
- speed: the old Matches() method had O(n^2) or even O(n^3) characteristics.
- improved control over how the mask is interpreted.
New types (for parameters) and a dedicated TMaskWindows class have been added.
TMask.MatchesWindowsMask and the old TMaskOptions type have been deprecated an will be removed in the next release.

TTaskDialog
- Old behaviour Win32: A placeholder icon was used for FooterIcon = tdiNone and MainIcon = tdiNone.
- New behaviour Win32: No icon is used for FooterIcon = tdiNone and MainIcon = tdiNone.
- Reason: Removing drawing glitch. The text move over to allow more content and better alignment. See Issue #39172

Changes affecting compatibility
Masks unit
- The old masks implementation supported sets, but not ranges. The new implementation supports both sets ([abc]) and ranges ([a-c]). As a consequence a '-' inside such a construct is now interpreted as part of the range definition, not as a literal '-'.
- Reason: ranges are a good thing to have by default (the old implementation simply lacked this). We decided it's a small price to pay.
- Remedy: either escape the '-' with EscapeChar (which defaults to '\') or exclude mocRange from the TMaskOpcodes parameter.
