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.

GPU_select originally used GL_SELECT which defined the format for
storing the selection result.
Now this is no longer the case, define our own struct - making the code
easier to follow:
- Avoid having to deal with arrays in both `uint*` and `uint(*)[4]`
multiplying offsets by 4 in some cases & not others.
- No magic numbers for the offsets of depth & selection-ID.
- No need to allocate unused members to match GL_SELECT
(halving the buffer size).
Replace `typedef` with `using` in C++ code.
In the case of `typedef struct SomeName { ... } SomeName;` I removed the
`typedef` altogether, as this is unnecessary in C++. Such cases have been
rewritten to `struct SomeName { ... };`
No functional changes.
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.
