This introduces CommandAllocator::AcquireCommandBlocks, which accepts a
vector of CommandAllocators and flattens them into a single iterable
sequence of commands. To support this, CommandAllocator is made movable.

Command buffers hold references to all encoded objects. Freeing them
eagerly significantly reduces the amount memory held before the JS GC
clears the command buffers.

Inlining these hot functions decreases CPU time in perf tests for
DrawCallPerf.Run/Vulkan by roughly 12% (55 to 47ns) and increases
binary size by about 0.16% (~4kB).

It was essentially checking "currentPtr + commandSize <= endPtr" and
commandSize could make currentPtr overflow, making the comparison
succeed when it shouldn't have. This was caught through flakiness of the
LargeCommands allocator test.
Added a test provoking an overflow in Allocate and checking nullptr is
returned.
