Remove SimpleLogProcessor from log benchmark

[lalitb]

Changes

Nit change to remove SimpleLogProcessor from the log benchmark. The benchmark is mainly for Logger and LogRecord, the result shouldn't be affected by the mutex lock for SimpleLogProcessor. Simple*Processor is only for testing purposes and can be avoided in general in bench tests. Or else, there can be a separate test for it if required.

Merge requirement checklist

• CONTRIBUTING guidelines followed
• Unit tests added/updated (if applicable)
• Appropriate CHANGELOG.md files updated for non-trivial, user-facing changes
• Changes in public API reviewed (if applicable)

LGTM (Please cleanup the NoOp processor to be NoOp, without even requiring an exporter)

CI errors due to updated rust toolchain. Will create a separate PR for this.
