clippy: Adjust large-error-threshold and remove waivers

[andyleiserson]

Increases the value of the clippy large-error-threshold setting from the default of 128 to 192, and removes waivers for the associated lint (which get applied at module scope, because otherwise they need to be applied to each function that uses the big error type, and would allow any error in that module to be arbitrarily large).

Errors that are between 128 and 192 bytes:

• back::pipeline_constants::PipelineConstantError
• ValidationError
• RenderBundleError, RenderPassError, CommandEncoderError
• (SubmissionIndex, QueueSubmitError)

Testing
Clippy is still happy.

Squash or Rebase? Squash (bonus points if you correct large_error_threshold to large-error-threshold in the commit message)

Checklist

• Run cargo fmt.
• Run taplo format.
• Run cargo clippy --tests. If applicable, add:
  • --target wasm32-unknown-unknown
• Run cargo xtask test to run tests.
• If this contains user-facing changes, add a CHANGELOG.md entry.
