  Fix and update to Freeze/Thaw, Move, and Rotate Label tools

Updates
- Move tool now preserves calculated x, y offset for upside-down labels, when initially moved and data-defined fields have no previous data.
- Move tool now stores the label's PAL solution for rotation on initial move, if rotation is data-defined with no previous data.
- Freeze/Thaw and Move tools now support all variations of previously data-defined halign and valign options on initial freeze.
- Freeze/Thaw tool has updated key modifiers that should work across major platforms.
- Tests for whether layer labels support data-defined rotation moved to base QgsMapToolLabel class.
Fixes
- Fix bug where labels defined in map units causing font to show as pointsize of same integer at small map scales.
- Half of a fix for rotation point of labels with data-defined size of map units actually being based off of point size.
  (still references the layer-defined font size somewhere in the rotation point calculation)
- Valign settings of Base and Half now more accurately key off of inverse of font ascent (instead of descent). No discernible shift occurs now on initial freeze.
