webgpu: Sync various parts of spec (#33009)

* Sync `GPUObjectDescriptorBase` (label is not option anymore)

Signed-off-by: sagudev <16504129+sagudev@users.noreply.github.com>

* Sync `GPUFeatureName`

Signed-off-by: sagudev <16504129+sagudev@users.noreply.github.com>

* shader_f16 feature is not usable in wgpu so disable it

Signed-off-by: sagudev <16504129+sagudev@users.noreply.github.com>

* sync `GPUTextureFormat`

Signed-off-by: sagudev <16504129+sagudev@users.noreply.github.com>

* `validate_texture_format_required_features`

Signed-off-by: sagudev <16504129+sagudev@users.noreply.github.com>

* Sync `GPUTexture` attributes

Signed-off-by: sagudev <16504129+sagudev@users.noreply.github.com>

* Make `entryPoint` in `GPUProgrammableStage` optional

Signed-off-by: sagudev <16504129+sagudev@users.noreply.github.com>

* Set good expectations

Signed-off-by: sagudev <16504129+sagudev@users.noreply.github.com>

* Bad expectations because naga does not support cons declarations

Also fail on firefox, where skipped before due to missing device features

Signed-off-by: sagudev <16504129+sagudev@users.noreply.github.com>

* Bad expectation, also fails on firefox

Signed-off-by: sagudev <16504129+sagudev@users.noreply.github.com>

* Bad expectations, because naga does not support `let pos = positions[vertex_index];`

Signed-off-by: sagudev <16504129+sagudev@users.noreply.github.com>

* Set expectation

external texture does not work in firefox too (again naga)

Signed-off-by: sagudev <16504129+sagudev@users.noreply.github.com>

* set bad expectations, because naga does not support `enable`

Signed-off-by: sagudev <16504129+sagudev@users.noreply.github.com>

* Set bad expectations for, `Texture with '' label has been destroyed`

also fails in firefox with same reason

Signed-off-by: sagudev <16504129+sagudev@users.noreply.github.com>

* one bad expectation

also on firefox

Signed-off-by: sagudev <16504129+sagudev@users.noreply.github.com>

* expect that also matches firefox

Signed-off-by: sagudev <16504129+sagudev@users.noreply.github.com>

* more expect

Signed-off-by: sagudev <16504129+sagudev@users.noreply.github.com>

* Use only 1 proc for _webgpu

Signed-off-by: sagudev <16504129+sagudev@users.noreply.github.com>

* better doc comment
