Fix ShaderF16Tests skipping on D3D12 when use_dxc is default

ShaderF16Tests::GetRequiredFeatures() only requested ShaderF16 on D3D12
if "use_dxc" appeared in forceEnabledWorkarounds. Since use_dxc became
enabled by default on D3D12 and test instantiations switched to
D3D12Backend() and D3D12Backend({}, {"use_dxc"}), all D3D12
ShaderF16Tests silently skipped.

Rely directly on SupportsFeatures({wgpu::FeatureName::ShaderF16}), since
ValidateFeatureSupportedWithTogglesImpl already rejects ShaderF16 when
use_dxc is disabled on the adapter.

[dawn] Simplify SerialProcessor interface

Remove AssumeCommandsComplete in favor of simply
UpdateCompletedSerialTo(kMaxExecutionSerial) which can be handled in a
more general way.

I think there could also be some conditions where this would make memory
get freed slightly sooner - immediately rather than waiting until the
next time the queue is flushed (if there is ever a condition that causes
a DeleteWhenUnused after the serial has already passed).

[tests] Suppress SharedTextureMemoryTests.WriteStorageThenReadSample …

…on Intel Xe2+ Linux

A compute-shader storage texture write to externally allocated memory
is partly lost on Intel Xe2+ GPUs with Mesa 26.0.8 and later on Linux
Vulkan. Some texels read back as zero.

Add IsIntelXe2OrLater() and fix IsIntelGen12OrLater().
