Fix negative shift in bitfieldExtract tests

Reference calculation was using a negative shift when the
number of bits for bitfieldExtract was zero. This is
undefined behavior so now the bits = 0 case is handled
separately.

Avoid division by zero in cube map coordinates

Cube map coordinates are calculated from 3-dimensional uv coordinates by
scaling two of the coordinates by the third. In case of using 0,0,0 as

This change detects the division by zero event and returns uv

Modify/add GLES XFB tests without element capture

Some GLES implementations are unable to support array elements as
transform feedback varyings. Capture the full array when element
capture is not explicitly tested. Add new variants for tests where
different types of varyings are tested at the same time.

Fix uninitialized index array

The test is doing a glDrawRangeElements using uninitialized data for
the element array. ANGLE validates that the indices fall within the
specified range. Data needs to be initialized to ensure that happens.

The spec says:
It is an error for index values (other than the primitive restart index,
when primitive restart is enabled) to lie outside the range [start, end], but
implementations are not required to check for this. Such indices will cause
implementation-dependent behavior.

Either the test needs to allow for an error or initialize the data so
as to be valid for the call.

Non-strict line interpolation and rasterization

Firstly non-strict line rasterization (parallelogram decomposed to
triangles) is changed to use the TriangleInterpolator do determine
interpolated colours. Line endpoint attributes are duplicated to the
end vertices of parallelogram lines, which means that interpolation is
not along the normal of the line, but would be parallel to the major
axis.

For the interpolation to be calculated correctly by the
TriangleInterpolator, the triangle geometry needed to be produced with
the correct w values from the line endpoints, previously the triangle
was generated pre-projected with 1.0 for the W-coordinates. The
perspective interpolation previously was calculated separately using
the original line parameters passed to MultisampleLineInterpolator.

The second part of the change is to allow for a non-strict line 'GLES'
centric relaxation - GLES specified 1px non-antialiased lines would use
the 'diamond-exit' rule to produce bresenham lines. Vulkan only
specified parallelograms, but not all GLES implementations are able
to disable the 1px bresenham behaviour.

Ensure alphabetical order of xml attributes

Python 3.8 removed artificial alphabetical ordering
of attributes in ElementTree. The recommended solution
to avoid changes in generated xml is to add attributes
in the alphabetical order directly in the source code.

fix input dependency for renderpass depth/stencil format tests

This appears to be a copy/paste mistake. The exact stage/access bits was
taken from other dependencies with an input attachment which is a
depth/stencil attachment.

Avoid exceeding maxPerStageResources in descriptor_indexing tests

The 'calculateInLoop; (*_in_loop) variant of the test is using additional
uniform texel buffer descriptor binding in pipeline layout.

This binding was counted only against maxPerStageDescriptorSampledImages and
maxDescriptorSetSampledImages limits, but not maxPerStageResources.

The fix is to count it against all three limits - but do this only when needed (in
*_in_loop) tests.

Split subgroupBroadcast tests

Subgroup broadcast tests with required subgroup size were
iterating the range of supported sizes in a single test.
These are now split into own test cases to prevent long
execution times of these tests and to allow the test
group to run faster when running tests in parallel.
