This patch adds a toggle to enable/disable workgroup memory
initialization with OpConstantNull according to the Vulkan extension
VK_KHR_zero_initialize_workgroup_memory. This toggle is by default
enabled when VK_KHR_zero_initialize_workgroup_memory is supported by
the Vulkan driver.

Introduces the majority of the logic associated with enabling
multiplanar external textures. Removes most backend logic associated
with external textures in favor of expanding them into their components
in the frontend. Includes a basic e2e test demonstrating multiplanar
YUV-to-RGB conversion.
