Check clearing of 3d textures when rendering to a slice (#4625)

• Check clearing of 3d textures when rendering to a slice

There was an issue in some browsers where, when rendering
to a slice of a 3d texture, they'd mark the entire texture
as initialized even though only the individual slice was
initialized.

Updated the tests so they check the entire texture.
Also updated them to try every format.

Test Reusing the same query in the same command buffer (#4626)

Queries are not allowed to be used more than once in
the same render pass but they are allowed to be used
more than once in the same command buffer, without
resolving inbetween use.

Add a test this works as expected.

Test uninitialized queries in unsubmitted command buffers (#4624)

• Test uninitialized queries in unsubmitted command buffers

Query slots that have never been used at required to resolve
to zero. Some implementaitons might wrongly mark them as
used at encoding time instead of submit time.

These failures could mean that the library update changed something and caused
tests to fail. You'll need to review them yourself and decide where to go from here.

In either event, I have done all I can and you will need to take it from here. If you
don't want to land my patch, you can replicate it locally for editing with
./mach vendor dom/webgpu/tests/cts/moz.yaml

When reviewing, please note that this is external code, which needs a full and
careful inspection - not a rubberstamp.

Comment 4

[Jim Blandy :jimb]

Down-prioritizing. Erich is on PTO, and we'll get a new bug filed by UpdateBot soon, which will fall on Andy's plate.

Comment 5

[Andy Leiserson [:aleiserson]]

Updatebot doesn't seem to have filed a new one, so I'll take over this one.

Comment 6

[Update Bot]

This bug is being closed because a newer revision of the library is available.
This bug will be marked as a duplicate of it (because although this bug is older, it is superseded by the newer one).
