[FEATURE] Introduces mesh virtual datasets
With the mesh calculator the user can choose to create those "virtual" dataset groups that will be added to the layer. Then, for these dataset groups, values are not stored in memory but each dataset is calculated when needed whit the formula entered in the mesh calculator.
Those virtual dataset groups are saved with the project.
If needed, the user can remove them or can persist them on files to make them persistent.

[FEATURE] Introduces memory dataset groups for mesh layer. These dataset groups are temporary and are not kept when the project is closed.
Memory dataset groups can be created from the mesh calculator with a new option.
Allows the possibility to remove or save these memory dataset groups to a file with specified driver.
* [MESH] [FEATURE] Sets meh color ramp classification from metadata read by MDAL driver.
Some mesh layer formats can provide values that can be compressed by categorizing values in consecutive intervals, each represent by an integer or byte. MDAL has the capabilities to recognize this dataset type and store the bounds of each class an the units in the metadata.
QGIS uses this metadata to setup adapted color ramp shader.
* [MDAL] update to pre-release 0.5.92
Allow load of multiple (sub-)meshes from a single file. If file contains multiple meshes (e.g. UGRID file), user needs to select the meshes to load from the dialog.
[infrastructure] [macos] use QGIS-Mac-Packager dependencies to setup MacOS CI build with GitHub workflows. Use CMake's define QGIS_MAC_DEPS_DIR to define folder to dependencies
* MDAL 0.5.90 : support for custom Logger and 1D meshes
* [FEATURE] [MESH] Support rendering of 1D meshes, see https://github.com/qgis/QGIS-Enhancement-Proposals/issues/164
1D mesh consist of edges (edge is straight line segment with 2 vertices) and the data that is defined on either
vertices or edges. Such data can be loaded by MDAL and rendered as mesh layer in QGIS.
[FEATURE] fix#31575 mesh layer speed rendering improvements (LOD)
As mesh layer could have millions of triangles, rendering could be very slow, especially when all the triangles are displayed in the view whereas triangles are too small to be viewed.
For those situations QGIS has an option to simplify the mesh. Simplification leads to one or more simplified mesh that represents levels of detail (LOD). When rendering the mesh, the appropriate level of detail is chosen to have an adequate rendering depending on the view.
Turns out this index is MUCH (magnitudes) faster for use in pal. So
grab an updated version of the upstream library and place in external libs,
and use this for indices in pal.
(we should probably investigate whether this is faster for snapping and
other index use too!)
