perf: performance improvements MTT-4641 #2176 (#2204)

jeffreyrainy · smitdylan2001 · web-flow · commit c5dff6d3fdbb · 2022-09-23T13:23:31.000Z
* Performance Improvement

- Merge if else into return
- Merge .rotation and .position into .SetPositionAndRotation
- Remove .ToString() call on strings
- Use TryGetComponent to reduce garbage allocation
- Merge .Where().Count() calls into .Count() call
- Remove indirect gameObject call 
- Remove redundant null check
- Use native .Count instead of LINQ method
- Use faster string comparison

* style: adjusting to code standards
