This adds support to render Curves attributes in EEVEE. Each attribute is stored in a texture derived from a VBO. As the shading group needs the textures to be valid upon creation, the attributes are created and setup during its very creation, instead of doing it lazily via create_requested which we cannot rely on anyway as contrary to the mesh batch, we do cannot really tell if attributes need to be updated or else via some `DRW_batch_requested`. Since point attributes need refinement, and since attributes are all cast to vec4/float4 to account for differences in type conversions between Blender and OpenGL, the refinement shader for points is used as is. The point attributes are stored for each subdivision level in CurvesEvalFinalCache. Each subdivision level also keeps track of the attributes already in use so they are properly updated when needed. Some basic garbage collection was added similar to what is done for meshes: if the attributes used over time have been different from the currently used attributes for too long, then the buffers are freed, ensuring that stale attributesare removed. This adds `CurvesInfos` to the shader creation info, which stores the scope in which the attributes are defined. Scopes are stored as booleans, in an array indexed by attribute loading order which is also the order in which the attributes were added to the material. A mapping is necessary between the indices used for the scoping, and the ones used in the Curves cache, as this may contain stale attributes which have not been garbage collected yet. Common utilities with the mesh code for handling requested attributes were moved to a separate file. Differential Revision: https://developer.blender.org/D14916
