  [WebGPU Swift] Fix crashing regression tests
https://bugs.webkit.org/show_bug.cgi?id=300510
rdar://162374042

Reviewed by Mike Wyrzykowski and Geoffrey Garen.

There were 8 crashing tests under fast/webgpu/nocrash caused by 3 separate small
bugs in CommandEncoder.swift:
- A call to Range using `(offset, size)` instead of `(start, end)`
- One remaining instance of `m_lastErrorString` being implicitly unwrapped when 
it
  was nil
- There was a bit of a confusion with the types used in `timestampWriteIndex`,
  so I cleaned it up, but I believe the real issue was the definition of
  `WGPU_MTLCounterDontSample` not matching `MTLCounterDontSample`. I'm not sure
  why the latter wasn't used originally, but it seems to work now.
