[FEATURE] Add order by support to expression aggregate and concatenation functions
...
Because certain aggregates and concatenation requires results in
a certain order, this change allows specific control of the order
features are added to the aggregate during an expression evaluation.
E.g.
concatenate("Station",concatenator:=',', order_by:="Station")
will give a comma separated list of station names in alphabetical
order, rather than layer feature order.

[FEATURE][expressions] Simplified variant of "attribute" function
...
This adds a second variant for the existing "attribute" function.
The current function requires both a target feature and attribute
name to be specified, while the NEW variant just uses the current
feature.
E.g.
NEW:
attribute( 'name' ) -> returns the value stored in 'name' attribute
for the current feature
EXISTING:
attribute( @atlas_feature, 'name' ) -> returns value stored in 'name'
attribute for the current atlas feature
It's just a faster shorthand version!
