Currently whenever gl queries are performed for the viewport, a large
1024 byte array is allocated to store the query results (256 of them).
Unfortunately, if any gizmo using a `draw_select` callback is active
(e.g. the transform gizmos), these queries (and allocations) will occur
during every mouse move event.
Change the vector to allow for up to 16 query results before making an
allocation. This provides enough space for every built-in gizmo except
Scale Cage (which needs 27 queries). It also removes unnecessary
allocations from two other related vectors used during query processing.

Use a shorter/simpler license convention, stops the header taking so
much space.

This is part of the Vulkan task T68990.
This introduce a new GLQueryPool for managing queries in an
implementation agnostic manner.
This modify the GPU selection query to use this new object.
This also make use of blender::Vector for better code quality.
No real functionnal change.
