This breaks fixing mesh layer paths when restoring projects with
broken mesh layers -- fixing the path causes the existing style
to be lost.
Fixes#45391
[mesh] UX fixes:
* move mesh elements click->move->click instead press-> drag->release
* allow to select by drawing a polygon and select an existing polygon in the same map tool like for vector layer)
[feature] [mesh] allows the user to make geom transformation of mesh frame by changing the vertices coordinates by expression. Each coordinates (X,Y,Z) of selected vertices can be calculated with an expression allowing transformation of the mesh while the mesh is still valid.

Move vector, project and network related core .cpp/.h files into
dedicated subdirectories.
An attempt to organise src/core better to make things easier to find.
[processing] Infrastructure for QgsMeshLayer to add processing algorithms, dataset group paramater and dataset time parameter to allow the user to easily choose a dataset.
The trust flag at the projetc level is only used to read vector layer extent from xml, not from provider.
This flag was not available at the vector layer and data provider level.
We propose a new QgsMapLayer reading flag to propagate the trust layer metadata prohect's read flag an d a new provider options to trust datasource config.
Trusting the datasource config means that the provider can use estimated metadata, the primary key is unique and the detectable geometry type and srid are the same as the requested.
[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.
