Vulkan: Improve cubemap emulation seam handling
Changes seamful cubemap emulation to always compute the derivative,
emulating the bias parameter by scaling the provided derivatives.
This results in more accurate mipmap levels for seams within primitives.
There are some artifacts as a result of how derivatives are calculated,
but this matches the native driver.

Vulkan: support dynamic indices in array of arrays
Expands existing struct-sampler rewrite to flatten arrays of arrays.
This allows us to support dynamically-uniform array indexing, which is
core in ES 3.2.
Samplers inside (possibly nested) structs are broken apart as before,
and then if the type resulting from merging the array sizes of the field
and its containing structs is an array of array, the array is flattened.
Also adds an offset parameter to functions taking in arrays to account
for this translation.
As a result of outer array sizes leaking into function signatures,
functions taking arrays of different sizes are duplicated according to
how the function is invoked.

Vulkan: Emulate subgroup ops in seamful cubemap emulation
Where subgroup ops are not available, they are emulated as such:
Code with subgroup ops:
float lH = subgroupQuadSwapHorizontal(layer);
float lV = subgroupQuadSwapVertical(layer);
float lD = subgroupQuadSwapDiagonal(layer);
bool isHelperH = subgroupQuadSwapHorizontal(gl_HelperInvocation);
bool isHelperV = subgroupQuadSwapVertical(gl_HelperInvocation);
if (gl_HelperInvocation)
{
layer = !isHelperH ? lH : !isHelperV ? lV : lD;
}
Emulated code:
float nonHelperLayer = gl_HelperInvocation ? 0.0 : layer;
float lH = abs(dFdxFine(nonHelperLayer));
float lV = abs(dFdyFine(nonHelperLayer));
float lD = abs(dFdxFine(lV));
float isHelperDiffH = abs(dFdxFine(float(gl_HelperInvocation)));
bool isNonHelperH = isHelperDiffH > 0.5;
float isHelperDiffV = abs(dFdyFine(float(gl_HelperInvocation)));
bool isNonHelperV = isHelperDiffV > 0.5;
if (gl_HelperInvocation)
{
layer = isNonHelperH ? lH : isNonHelperV ? lV : lD;
}
Both paths are supported as on nvidia devices the emulated code
misbehaves. This change therefore effectively only enables seamful cube
map emulation on Android where subgroup operations are not supported.

Vulkan: Seamful cube map emulation
In GLSL, a cube texture is sampled with one of textureCube* functions.
This function takes a 3D coordinate which is a vector from the center of
the cube and identifies a direction to sample from. GLES2.0 has the
following table that translates this 3D coordinate (Rx, Ry, Rz) to a
face and ST coordinates within that face. This table can be found in
Section 3.7.5 (Cube Map Texture Selection).
A compiler pass is implemented in ANGLE that replaces samplerCube
declarations with a sampler2DArray. The textureCube* functions are
replaced with the corresponding texture* functions with the translated
coordinates according to that table.
Gradients provided to textureCubeGrad are translated using the same
formulae, which is not precise but the spec specifies this projection to
be implementation dependent.
Helper invocations enabled through WQM (whole quad mode) cause a
nuisance in that the extrapolated varyings used as coordinates in a
textureCube call could have a different major axis (and therefore face)
from the non-helper invocations that lie within the geometry.
subgroupQuadSwap* operations are used in conjunction with
gl_HelperInvocation to make sure the helper threads calculate texture
UVs in the same face as the non-helper invocations.

Vulkan: Rework layout block storage conversion
Previously, a pass over the shader was made, converting shared and
packed interface blocks with block storage to std140. This resulted in
link success between interface blocks with different storage as they
were all translated to std140.
With this change, this pass is removed. The link step proceeds with the
block storage specifiers as seen by GLES, and only upon Vulkan GLSL
shader generation "shared" and "packed" are converted to std140.

Vulkan: Implement EXT_draw_buffers
In GLES, color attachments are referenced by their indices. These
indices match between the API and GLSL. For example, if a shader has:
layout(location=0) out color;
layout(location=3) out roughness;
Then GLES would bind and enable GL_COLOR_ATTACHMENT0 and
GL_COLOR_ATTACHMENT3.
In Vulkan, the framebuffer object and the corresponding renderpass
define the color attachments, and they don't allow gaps in color
attachments as GLES does. A render subpass creates the mapping between
the color attachments as defined in the framebuffer and the attachments
used by the shader (with possible gaps).
This change packs the enabled GL color attachments for the sake of the
framebuffer, and sets the subpass up in such a way that the shaders
continue to use the same color output indices as GLES.
In the example above, we have the attachment indices as follows:
Status | GLES | GLSL | RenderPass | Subpass
enabled 0 0 0 0
disabled 1 - VK_ATTACHMENT_UNUSED
disabled 2 - VK_ATTACHMENT_UNUSED
enabled 3 3 1 1
That is, the array of color attachments in the Vulkan
framebuffer/renderpass is:
[0] = GL color attachment 0
[1] = GL color attachment 3
And the array of color attachment references in the Vulkan render
subpass is:
[0] = 0 (index 0 of the renderpass attachment array)
[1] = VK_ATTACHMENT_UNUSED
[2] = VK_ATTACHMENT_UNUSED
[3] = 1 (index 1 of the renderpass attachment array)

The program compilation tests work now, but don't really test
anything other than not generating Vulkan validation layer errors
during compilation and shader object generation.
