Optimize HandleAllocator for fast ID churning.
Instead of calculating ranges of IDs and the overhead with updating
them every allocation/release, store a released ID list in a small
FastVector.
Optimize the allocate path for the "good case" of no reserved IDs so
that it either pops the last released ID or incriments a next value and
returns it. Release has a similar cost of just a push_back when there
are no reserved IDs.
This adds a small fixed memory cost due to the FastVector and a dynamic
memory cost of mReleasedList having up to N elements where N is the
maxmimum total handles allocated at one time.

Vulkan: Separate out XFB data from ShaderInterfaceVariableInfo
Right now the transform feedback data is embedded in the
ShaderInterfaceVariableInfo. This caused ShaderInterfaceVariableInfo
becomes non-trivial copy-able. This CL moves transform feedback related
data out and into its own array, and entire vector of
ShaderInterfaceVariableInfo is now memcpied. Further, most programs
don't use transform feedback. Right now because transform feedback data
is embedded in the ShaderInterfaceVariableInfo, it bloated the size of
ShaderInterfaceVariableInfo even if you do not use XFB. This CL makes
transform feedback variable info data a std::unique_ptr so that if not
used, it is just a nullptr. When we load/save the structure, the ones
that has nullptr gets skipped.

Fixed bugs in "FastVector" class.
Bugs:
- items resources may not be freed after resizing to a lesser size.
- reusing capacity may use old values for the new items.
Fixed by resting removed items to default values.
Alternative fix is to disallow dangerous operations on non trivially
constructible/destructible types.

Vulkan: Track used Images in RenderPass.
Adding a simple ImageSerial tracking map in our RenderPass allows us
to know when we do or do not need to close the RenderPass on a new
Image access. This simple tracking scheme improves Manhattan
performance by up to 25% on Android. The improved perf comes from
reducing our RenderPass count (23->18 RenderPasses in our capture
scene).
Adds a FastUnorderedSet class to manage the used RP Image serials.
Updates the Query helpers to explicitly flush the RP before inserting
queries.

Vulkan: Optimize resource tracking in CommandBufferHelper.
Introduces a FastUnorderedMap class that uses FastVector. This type
uses static storage for up to a small fixed number of elements and
uses dynamic storage for anything larger.
Local testing shows this almost fully solves the regression from
using unordered_map. It's still slightly slower than using no
tracking (<5%).
Very degenerate cases which track dozens or more buffers will still
have significant overhead. For almost all applications that use only
a few buffers per RenderPass this will be very fast.

Re-land "Add FastVector for simple dynamic vector cases."
Re-land fixes memory leak and adds inline to a few more methods.
This optimized vector keeps an initial fixed size storage but has
unbounded growth like a normal std::vector. It operates like a
FixedVector initially but then switches the storage to an allocated
pool when the element count exceeds the array limit.
This gives fast performance in the small case since no dynamic
allocation is needed. It also handles the "slow" big case.
