Vulkan: Remove asyncCommandQueue
It's been years and it never showed an advantage. In the meantime,
performance without this feature seems close to native drivers (i.e. the
feature has lost its appeal) and it's frequently a source of
complication and bugs.

Vulkan: Update SharedCommandBlockPool::valid() method.
Current logic returns `valid()` result whether `mAllocator` is
attached or not. However this is not correct, because it is allowed
to use some method even after allocator is detached.
Since this class does not require initialization - it is always valid.

Vulkan: Cleanup shared ring buffer cmd alloc feature.
Changes:
- Simplified "SharedCommandBlockPool" interface.
Removed "ptrOut" and "usesCommandHeaderSizeForOffsetOut" parameters,
because "headerOut" has exactly the same value.
- Refactoring of "SharedCommandBlockPool" classes.
Some public methods made private, inline, or moved into ".cpp".
- Replace some getters with more specific/restrictive methods:
- "RingBufferAllocatorBuffer::getStorageSize()" -> "isEmpty()"
- "CommandBufferHelperCommon::getAllocator()"
-> "hasAllocatorLinks()"
- Added extra ASSERT()s.
- fixed typo "kMinRingBufferAllocatio(r)Capacity"
- other minor modifications.

Vulkan: Add shared ring buffer cmd alloc feature
* Added RingBufferAllocator.cpp with implementation.
* Main classes:
* RingBufferAllocator (fast allocation with bulk deallocation)
* SharedRingBufferAllocator (wrapper to help with shared use and
multiple threads)
* Implemented "angle_enable_vulkan_shared_ring_buffer_cmd_alloc"
feature. (Disabled by default)
* Details (from the original CL)
* The angle::PoolAllocator replaced with
angle::RingBufferAllocator.
* Before, there was separate angle::PoolAllocator per each
CommandBufferHelper. Now, a single angle::RingBufferAllocator
is shared between multiple CommandBufferHelper objects.
* Commands data from multiple CommandBufferHelpers is
tightly packed without fragmentation.
* Significantly less memory overhead, observed with enabled
async queue.
* Moved the parts of the code related to the allocators into the
classes in the new AllocatorHelperPool and AllocatorHelperRing files
for better management. The allocator can be switched by changing the
following BUILD flag:
`angle_enable_vulkan_shared_ring_buffer_cmd_alloc`
* It is connected to the following macro:
ANGLE_ENABLE_VULKAN_SHARED_RING_BUFFER_CMD_ALLOC
* The two main allocator classes in each file are aliased as:
* SecondaryCommandBlockAllocator (in CommandBufferHelper objects)
* SecondaryCommandBlockPool (in SecondaryCommandBuffer)
* Also added placeholder functions for VulkanSecondaryCommandBuffer.
* Added descriptions regarding the two allocators.
