* Fixed ASan issue with dirty data (weightmap/heightmap texture resolving debugging code) by removing usage of lambda in favor of direct call to the dirty function
* Fixed redundant ifdefs and invalid comments
* Removed overallocation of material instances array (was previously done to account for hardware tessellation which doesn't exist anymore)
* Renamed FLandscapeEditLayerReadbackResult to FLandscapeEditLayerComponentReadbackResult to better match what it actually is and changed the output type of readback results from ResolveLayersTexture from a map to an array, because a map was overkill and it allows to batch-handle readbacks in UpdateForChangedWeightmaps / UpdateForChangedHeightmaps

The rendering of the 4 landscape components is needed for passes (like RVT) where Nanite is not supported or implemented, and we only want the Nanite landscape component to render in the base pass and virtual shadow maps. (mutually exclusive).
I've now implemented a new mutually exclusive render state that each proxy propagates down to the landscape components to override the calculated view relevance without destructively changing properties like bRenderInMainPass (since we don't want to break non-Nanite rendering when Nanite is not supported by the runtime or platform).

Landscape: added utility function to render the merged heightmap from anywhere in world space. This is done in 2 steps : render the heightmaps of all landscape components overlapping with the requested region into an atlas texture (uncompressed) subsection by subsection, skipping the duplicated rows/columns. Then resample the atlas at the requested location.
If the render target is 8bits/channel, the resulting heightmap will be compressed on the R and G channels. If the target is 16 bits uint, the output will contain the uncompressed height value.
The function supports heightmaps with different minimum mip level and will use the best available mip level. However, currently the intermediate atlas render target is always allocated using the landscape's full resolution.
This is meant to be compatible with runtime but is not at the moment, because it relies on ULandscapeInfo members which are not editor-only but are not available at runtime (yet). This will be fixed later on.

Also fixed a couple of places where we were not using the FTextureSource's data (even though those calls should be fine since they happen in a place where texture compilation is done)

This meant that the test in ALandscapeProxy::PostRegisterAllComponents() to know whether data migration (from non-edit layers to edit layers) should occur, which relies on the cached value bHasLayersContent (which was always false in that case, since there's no landscape component in the ALandscape) and the result of virtual function HasLayersContent() (overridden in ALandscape::HasLayersContent to return true if there's at least one registered landscape edit layer) was always forcing data migration to occur, which would do nothing (no landscape component, hence, no data to migrate) but was still marking the level as dirty

Added a new registry to let the objects provide how their elements should be selected when doing a selection by a volume such as a box or a frustum.
Added a some editor only functions for the marquee selection into the world interface.

Fixes uninitialized member in FLandscapePerLODMaterialOverride

#preflight 6220c3397e0217a606ee7545
Original CL Desc
* Removed incomplete per-platform per-LOD level material overrides for landscape. The code isn't meant to support that since material instances are built at edit-time. We would need to somewhat hack it at cook time in order to regenerate (and recompile) the list of material instances per-platform, which is not a recommended thing to to in the engine. Instead, we choose to simply make the per-LOD level material overrides constant across platforms since the recommended way is to customize the material for platforms using material expressions such as Quality Level switc, Shading Path Switc or Feature Level Switc.
* Deprecated/merged FLandscapeComponentMaterialOverride and FLandscapeProxyMaterialOverride into FLandscapePerLODMaterialOverride since they were identical
* Fixed UpdateLayersMaterialInstances which, unlike UpdateMaterialInstances, didn't take into account per-component material overrides
