This introduces a new option for specifying how raster layers
have associated elevation. It permits a fixed elevation range
to be set for the layer. It can be used when the layer has
a single fixed elevation, or a range (slice) of elevation values.

Users can set the lower and upper elevation range for the layer,
and whether the lower or upper limits are inclusive or
exclusive.

When enabled, the layer will only be visible in elevation
filtered 2d maps when the layer's range is included in the map's
z range.

Allows forcing the widget to have a specific fixed range width,
so that interactions with the lower or upper slider automatically
force the other slider to move to keep a constant width

This ensures that the labels don't overlap when the selected range
is narrow

This adds a new option to the configure menu for the elevation
controller, for setting a fixed elevation slice width. It can be
used when a specific elevation range width is desired, or when
the range should always be zero width.

In this mode, each band in the raster can have a fixed elevation
range associated with it. This is designed for data sources which
expose elevation related data in bands, eg netcdf files, such
as a raster with temperate data at different ocean depths.

This is exposed as a user editable table of raster bands with
lower and upper values. Users can either populate the lower
and upper values manually, or use an expression to auto fill
all band values based on a qgis expression.

The expression based fill allows for users to design expressions
which extract useful information from band names, eg extracting
the depth value from a "Band 001: depth=-5500 (meters)" style
band name.

Server/OAPIF: fix unreported issue with access control layer permissions

[qml] Add a couple of Q_INVOKABLE in QgsProject and QgsVectorLayer to ease layer and feature fetching + editing

Note that not all fonts available from Google fonts are present on
the github repo for some reason, eg Open Sans Condensed is not.

Fixes qgis#57070
