D3D12 requires more buffer storage than it should. If the buffer used
for B2T/T2B copy is big enough according to WebGPU spec but it doesn't
meet D3D12's requirement, we need to workaround it via split the copy
into two copies, in order to make B2T/T2B copy being done correctly on
D3D12.

The current presubmit has the filter inverted so it would only attempt
to match the filtered files. The file name also has to be converted to
`LocalPath` otherwise it's attempting to compare a python object to a
string and always fails to match.

This adds a test, and a toggle disable_resource_suballocation.
This enables testing the behavior discovered in the bug without
creating enormous resources.

This patch adds a toggle to enable/disable workgroup memory
initialization with OpConstantNull according to the Vulkan extension
VK_KHR_zero_initialize_workgroup_memory. This toggle is by default
enabled when VK_KHR_zero_initialize_workgroup_memory is supported by
the Vulkan driver.

Although the error rate of timestamp tick->ns conversion is very small
(3e-5), some profiling scenarios, such as CPU/GPU timestamp calibration
on Windows, require absolutely accurate timestamps.
Add new toggle to resolve timestamps to ticks for those cases where zero
error is required.
Add an end2end test for GPU timestamp calibration on D3D12 backend.
Disable timestamp period calculation on Device when the
DisableTimestampQueryConversion is enabled.
