[SYCL][Doc] Fix small typos in sycl_ext_oneapi_reusable_events (#22881)
- "event `e`" changed to "event `evt`" since that is the param name
- `event:wait` changed to `event::wait`
- "compete" changed to "complete"
- "reassociated" changed to "reassociate"
- `property::queue::enable_profiling property` changed to
`property::queue::enable_profiling` property
- "creates SYCL event" → "creates a SYCL event"
- "function cannot" → "functions cannot" (multiple funcs in the
sentence)
