5b244ae88c [FEATURE] More geometry functions for expressions 
- add accessors: geometry_n, interior_ring_n
- add num_geometries, num_rings, num_interior_rings
- add nodes_to_points for converting every node in a geometry
to a multipoint geometry
- add segments_to_lines for converting every segment in a geometry
to a multiline geometry

nodes_to_points and segments_to_lines are intended for use with
geometry generator symbology, eg to allow use of m and z values
for nodes/lines with data defined symbology.

55027e545f Clean up and extend expression geometry functions: 
- New expression functions for area(geom), perimeter(geom),
point_n(geom), start_point(geom), end_point(geom), make_point(x,y)
- Add new variant to length() function which takes a geometry object,
allows for length(geom) evaluation.
- Rename x_at, y_at to $x_at, $y_at (alias old names) to reflect that
these only work on current feature geometry
- Add x(geom), y(geom) functions which return x and y coordinate
for point geometries or centroid x/y for non-point geometries
(fix #11008)

709c14391b Change expression help from free form html files to structured json 
A new script then parses these json help files into the html help
contents, in a standardised manner. Previously, the function help
was a bunch of different formats and structures.

Now, a custom stylesheet can be applied (and later tweaked!) to
format these help. Eg, this commit colors variables and function
names in the syntax section for greater readability.

7871d6c5fc Remove a bunch of layer variables, replace with new layer_property 
function

layer_property takes a layer name/id and a property (eg 'crs')
and returns the matching value. This approach is more flexible than
having all these values as variables, since it allows retrieval
of properties of a layer from contexts which aren't layer-aware
(eg a composer label showing the metadata of a layer).
