Vulkan: Fixed Context Priority mixing problems. Problem details: - Each "egl::ContextPriority" may have separate "VkQueue". - "CommandQueue" only has two "PrimaryCommandBuffer"s for normal and protected content. - Commands from multiple "ContextVk" may be written to a single "PrimaryCommandBuffer". - That "PrimaryCommandBuffer" may be randomly submitted to different "VkQueue"s. - As the result - Commands from a single "ContextVk" may be submitted to multiple "VkQueue"s. Fix details: - Created separate "PrimaryCommandBuffer" (lazily allocated) for each "egl::ContextPriority". - Commands with different priorities can't be mixed in a single "PrimaryCommandBuffer". - Therefore - Commands from a single "ContextVk" will be submitted to a single "VkQueue". - No difference for applications that use single "egl::ContextPriority" for all Contexts. Notes: Another problem when resource is used in multiple Contexts with different "VkQueue" (Priority). One solution is to use Semaphores. Another is to enfore same Priority for all Contexts in a Share Group and Default Priority when using EGLImage. This solution was submitted in the previous CL: Vulkan: Enforce ContextPriority in ShareGroup and with EGLImage Below test fails on G996B without this CL.
