Removes location calculation from buffer and feature flag

[desaikd]

Issue #, if available:

Description of changes: This PR removes the previous implementation for location calculation in text buffer. It also removes feature flag lazy-source-location since the current implementation for location shows performance as close to main branch.

List of changes:

• Removed all implementation of location calculation in text buffer.
• Removed lazy-source-location feature flag from current implementation. The performance for lazy /current approach is close to the main branch(~2% regression to main branch, only for scanning data, for reads same performance)

Benchmarks: Lazy Bookkeeping on Flushes (compared to old text buffer solution (#922))

• Significant performance improvements over previous implementation of location support
• Scan operations: ~17% improvement
• Read operations: ~15-16% improvement
• Read 'format' field: ~16-17% improvement
• Performance nearly matching main branch across all operations
