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)

Vulkan: add uniform buffer object support
Support for layout qualifiers in interface blocks are added. All
interface blocks are adjusted to either be in std140 or std430.
In the Vulkan backend, a new descriptor set is added for UBOs. A dirty
bit is added for UBO updating and pipeline layouts and descriptor
bindings are updated.

Vulkan: Implement shader compilation.
This hooks up the Vulkan GLSL, decorated with locations, to glslang,
and then pipes the SPIRV back to the Program implementation for later
use when making pipelines to run draw calls.
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.
