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.

Due to the freeing and re-creation of textures performed when binding
offscreen viewports, VR viewport textures would be needlessly
re-created every drawing iteration, leading to a negative impact on VR
frame rate.
This was brought to light by 6738ecb64e, which introduced an
additional texture clear operation on initialization and was
prohibitively costly on some systems when performed every frame.
Now, the textures for VR viewports will not be always re-created
during offscreen binding, but only when necessary using a pre-drawing
step (`wm_xr_session_surface_offscreen_ensure()`).

Ref D14069
A Bump node without a Height input is meaningless and does nothing.
As such, it is available as an old workaround that allows making Node
Group inputs that default to normal when not connected, by routing
via a no-op Bump node before doing math.
Cycles specifically recognizes this use case and either bypasses
the node, or converts it into a Geometry Normal node, but Eevee
was still evaluating it as usual. That incurred performance cost,
and also normalized the vector unlike Cycles.
This implements the same bypass logic for Eevee. Since I'm not
sure if it's possible to totally remove the node at this stage,
it emits a no-op function call to copy the input vector.

- Fix image.format conversion to string
- Fix warnings about ARB_conservative_depth not found even if GL > 4.2
- Add `array(type)` define for portable array definition
Thanks to the new `ShaderCreateInfo` we now include source files without
any modification. This let us query which are the source files passed to the
`print_log` function. The log will now include a file with row and column
number which is interpreted as a link in most IDE.
DEBUG_CONTEXT_LINES will add more lines around the error lines for more
context. This is also useful if the error line is imprecise (because of
driver bugs) and the reported line is not sufficient to know the location
of the error.
The DEBUG_DEPENDENCIES option will display the list of included files in
the shader sources. Note that it will not print generated source.
This commit also fixes some issues with unhelpful logs, bogus row & column
numbers, other error format, and bug if row was 0.
Source files are now only referenced and listed for the driver to ingest.
Shader sources now includes generated data if any.
Also cleans up gpu_shader_dependency_get_builtins casts.
This includes multiple commits:
- Fix crash when using std::cerr for error output
- Add auto_resource_location which overrides all resources location (not vert input)
- Improve codestyle of error reporting.
- Add type conversion to string and to `eGPUType`
- Add comparison operator (will be used for hash collision resolution).
- Add members related to generated code (codegen)
Detected on `amdgpu-pro` libGL implementation. The workaround is to not
use explicit location for vertex attributes. This is not a real problem
as we don't rely on them for now.
This was caused by macros interpreted as recursive. Workaround by
not using macros at all and just define local variables which
hopefully will be optimized.

Using opt-in instead of opt-out to make code easier to read.
Add combined flag enum.
Making restrict an inverse flag option because it is so rare to
use it.
This adds the possibility to use the `gpu_BaryCoord[NoPersp]`
builtin to support barycentric coordinates without geometry shader.
The `BuiltinBits::LAYER` builtin needs to be manually added
to the `GPUShaderCreateInfo` in order to use this feature.
Note: This is only available for shaders using `GPUShaderCreateInfo`.
A geometry shader fallback is generated if the extension
`AMD_shader_explicit_vertex_parameter` is not available.
`NV_fragment_shader_barycentric` was not considered because it is not
present inside the `glew.h` with use and seems to only be available
with vulkan.
This adds the possibility to use the `gpu_Layer` builtin to
support layered rendering without geometry shader.
