[cwfitzgerald]

Checklist

• Run cargo clippy.
• Run RUSTFLAGS=--cfg=web_sys_unstable_apis cargo clippy --target wasm32-unknown-unknown if applicable.
• Add change to CHANGELOG.md. See simple instructions inside file.

Description

Two standalone commits:

• Make doctests and tests run wgpu-types' tests.
• Fix issue where explicitly spelled out full-resource views would not work correctly, causing metal validation to get mad when the surface texture was used this way.

Testing

Tested against rend3, and with explicit doctests.
