Merge #1576

1576: Switch all bitflag names to plural r=cwfitzgerald a=kvark

**Connections**
#1471 added a lot of singular bitflag names. Previously, we weren't really consistent.

**Description**
This PR changes all of the names to be plural, except for a few that don't imply singularity, and are matching WebGPU upstream. Maybe we need to convert them too?

**Testing**
self-tested
