f80a33be65 [FEATURE] Expose @parent variable in aggregate functions 
This makes it possible to access attributes and geometry from the parent
feature when in the filter of the "aggregate" expression function.

With this in place aggregates can be calculated per feature.

E.g. max "measurement" for each point_station per polygon_research_area.

Or a default attribute value when digitizing features:

    aggregate(layer:='countries', aggregate:='max', expression:=\"code\",
filter:=intersects( $geometry, geometry(@parent) ) )

01f3c9ae38 [FEATURE] Add is_selected and num_selected functions 
* is_selected() returns if the current feature is selected
* num_selected() returns the number of selected features on the current layer
* is_selected(layer, feature) returns if the "feature" is selected. "feature"
  must be on "layer".
* num_selected(layer) returns the number of selected features on "layer"

8589788544 Use QgsExpressionContextScope::addVariable instead of setVariable 
...where appropriate (ie, read-only, non user set variables).
It's much faster as it doesn't need to check whether the
variable already exists.

Results in ~10% improvement in rendering speed. Refs #15752.

49432a8468 Optimise QgsAbstractGeometry 
Make nCoordinates virtual, and provide shortcuts for some
geometry types. The base method which calls coordinateSequence()
is quite slow in certain circumstances.

Speeds up rendering point layers by ~25%, also likely to
speed up lots of geometry heavy operations throughout QGIS
