Add force_polygon_cw and force_polygon_ccw expression functions
...
These are recommended for use instead of the existing force_rhr
function, due to the variability in definition of the "right hand
rule" between different software applications. Using an explicit
force_polygon_cw/ccw function removes user confusion when the
results vary between different applications.

[feature][expression] Add a "per_part" option to "rotate" expression
...
function
If set to true and no explicit rotation center point is specified (ie
rotation happens around the geometry's center), then the rotation
is applied around the center of each part individually instead of the
geometry as a whole.
This is designed mostly to aid cases when rotate is used as a cartographic
tool as part of a geometry generator symbol layer.

[feature][expressions] Add new apply_dash_pattern function.
...
Applies a dash pattern to a geometry, returning a MultiLineStringi
geometry which is the input geometry stroked along each line/ring
with the specified pattern.
Rules can be set to control how the dash pattern is adjusted
at line endings. If a start rule or end rule is set, the adjustment
option defines whether both dash and gaps, or only dash or gap
sizes are adjusted to apply the rules.
An optional pattern offset can specify how far along the pattern
the result should start at.
(The offset is applied AFTER any start/end rules are applied.)
