Instead of always calculating the scale along the bottom of the
map, expose a choice of methods to the user (along bottom,
middle, top, or average of the three measurements)
For new scalebars, default to the average method, which better
handles the scenario where the scale at the top or bottom of
the map cannot be calculated (eg when the top/bottom of the map
falls just outside valid areas for the map's crs)
This fixes one of the most common scenarios which cause scale
bar widths to blow out to massive sizes

as distinct symbols vs the scalebar line symbol
Allows for styling division and subdivision symbols in a different
way compared with the horizontal line symbol in a tick scalebar

standard QGIS line symbols
Instead of the previous settings of scalebar line color/width/cap styles,
we now expose the option as a full line symbol for more advanced styling
Also some code cleanups

Gives users control over all the formatting properties for the numbers
in scalebars, including whether they want thousand separators, decimal
places, scientific notation, etc
Fixes#21341
exporting to a multi-layer format
Now, items are either
- placed onto the same layer as other items (simple items like labels, lines, pictures)
- placed onto the same layer as only other items of equal types (semi-complex items like scalebars or pages)
- placed onto their own unique layers (complex items like legends, maps)
Plus lots of tests covering this, where previously there was few
Adds a new visitor pattern API for creation of visitors which visit
all the style entities (symbols, color ramps, text formats, and
label styles) associated with different objects. Can be used on a
renderer, map layer, or project wide level.
E.g. on a project wide level, allows collection of ALL the style
symbols/color ramps/text settings inside a project, including those
in layouts or annotations!
Checks whether a function declaration has parameters that are
top level const.
const values in declarations do not affect the signature of a
function, so they should not be put there.
