- Restrict source texture must have |CopySrc| and |Sampled| usage.
- Restrict destinaton texture must have |CopyDst| and
|RenderAttachment| usage.
- Restrict sample counts of source texture and destination texture
must be 1.
- Restrict source copy origin.z must be 0.
- Restrict CopyTextureForBrowser() can only copy to single slice.

This CL adds two helpers for more ergonomic processing of
ChainedStructs.
1. FindInChain(): Iterates through the chain and automatically
casts the ChainedStruct into the appropriate child type before
returning.
2. ValidateSTypes(): Verifies that the chain only contains structs
with sTypes from a pre-defined set. This also allows the caller
to specify one-of constraints.
3. ValidateSingleSType(): Verifies that the chain contains a
single struct with a specific sType or is an empty chain. This
is a common case of |ValidateSTypes()| and is separated out as
a fast-path.

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.
