This patch implements buffer lazy initialization before writeBuffer():
if the buffer is not initialized and writeBuffer() doesn't cover the
whole buffer, the buffer will be cleared to 0, otherwise the buffer
shouldn't be cleared.
This patch also introduces a toggle LazyClearBufferOnFirstUse for the
development of buffer lazy initialization: before buffer lazy
initialization being completely supported, all the related code will
only be enabled behind this toggle to prevent the buffers with valid
content being unexpectedly cleared.

Explicit enums are simpler to use in Dawn and allow only specific
categories which the perf tests understand.
Also adds trace events around command recording and validation on
all backends.

This required putting Queue::Submit on QueueBase which is something we
would want to do anyway, and removes the need for Queue::ValidateSubmit
being called in the ProcTable.
This removes the need for all the "GeneratedCodeIncludes" files and
leads to a bunch of simplifications in BindGroup as well as the
dawn_native CMakeLists.txt.
Finally this was done in order to simplify the writing of BUILD.gn
files.
