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.

Currently the Chromium build defines a wrapper build target
for Dawn (//chrome/test:dawn_perf_tests) that seems to exist
only to specify some extra data dependencies. By moving this
data dependencies onto the Dawn dawn_perf_tests itself, this
removes a problematic target in Chromium that would otherwise
block my planned changes for crbug.com/816629.

No test is added because SetSubData will be removed soon, and it will be

of different types from being used interchangably in Debug builds.
It also adds ityp::{array,bitset,span} as helper classes to wrap std::
versions (not span). These accept a template paramter as the Index type
so that typed integers, or enum classes, may be used as a type-safe
index.
For now, bind group layout binding indices use TypedInteger. Future

Retrieval filter was receiving errors that shouldn't be
stored or not storing new errors. Since these errors are
never reaching the storage filter or being stored without
being filtered, this workaround removes the storage
filter entirely and filters them upon being retrieved.
After the change, two new E2E tests fail
backend validation and require further investigation.
