Yunchao He daffd22b68 Add validation rule for depth/stencil between pipeline and pass
depthWrite/stencilWrite in DepthStencilState in RenderPipeline
should be compatible with depthReadOnly/stencilReadOnly in
DepthStencilAttachment in RenderPass. Otherwise, you may need
to generate validation errors.

Brandon Jones bb417ace11 Validate index formats in SetIndexBuffer
Fuzzer discovered that it was possible to send invalid IndexFormats
to SetIndexBuffer and cause IndexFormatSize to hit an UNREACHABLE().
This validates that the passed format is part of the enum before
doing any further operations on it.

Ken Rockot ebf183bde4 Implement drawIndexedIndirect validation
Every render pass which invokes DrawIndexedIndirect, either directly or
through a RenderBundle execution, is now preceded immediately by at
least one validation pass.

All indirect buffer offests used with DII are validated, and their
validated values are copied into a separate scratch buffer (or zeroed
out there, in the case of validation failure). All encoded DII commands
are rewritten to use the validated parameters instead of the original
ones.

Ken Rockot 44d729fc8c Introduce BufferLocation
This is a simple RefCounted holder of a Buffer ref and offset. Encoded
commands can store a ref to this object instead of directly storing an
inline Buffer ref and offset, allowing other commands to dynamically
patch in a different buffer+offset as needed, in a memory-safe way;
as opposed to e.g. retaining an unmanaged pointer to the encoded
command itself and modifying it in-place.

Validation commands will use this to rewrite buffer references in
encoded commands, so that they execute over validated inputs rather
than over their original client-provided inputs.

No net functional changes in this CL, just some groundwork for indirect
draw/dispatch validation.

In this patch OOB validation in draw and drawIndexed is added for vertex
buffer with zero array stride. For such case, both vertex step and
instance step mode buffer can be validated for both draw and drawIndexed,

Corentin Wallez ec7ea6aaaa Separate the types for compute and render pass usage data
This change is a preparation for making the compute pass track the
synchronization scope usages per dispatch instead of for the whole pass.

This CL just separates the Compute and RenderPassResourceUsage types.
This requires making the difference between
SyncScope/ComputePass/RenderPass ResourceUsageTracker instead of having
a single combined tracker.

This change also duplicates SetBindGroup by removing the common handling
in ProgrammablePassEncoder and putting it in ComputePassEncoder and
RenderEncoderBase. This is necessary because the UsageTracker types are
now split, but it will also help have different handling of SetBindGroup
for compute and render in follow-up CLs.

There are no functional changes.

Austin Eng 69f1db7248 Add RenderEncoderBase to match WebGPU class hierarchy.
This is needed so that RenderBundleEncoder and RenderPassEncoder can
share code. This patch also moves EndPass out of ProgrammablePassEncoder
and into both RenderPassEncoder and ComputePassEncoder. Render bundles
do not have EndPass.
