perf(logs): avoid string allocation when no parameters are passed

[Flash0ver]

Noticed during getsentry/sentry-unity#2389.

Avoid a string allocation when there are no parameters that the template string should be formatted with.

TODO:

• after v6
• a quick benchmark could not confirm the performance improvement ... need to follow up after v6 release
