Refactor kernel implementations for performance optimization

[LoserCheems]

Summary

• This update optimizes the performance of various kernel implementations and enhances synchronization in benchmark comparisons.

Root Cause

• The previous configurations and implementations did not fully leverage performance optimizations available in the kernel code.

Changes

• Refactored autotune configurations across multiple files to improve kernel performance.
• Adjusted the dot kernel implementation for better efficiency.
• Added synchronization calls in the benchmark function to ensure accurate output comparisons.

Reproduction

• No specific bug to reproduce; this is an enhancement.

Tests

• Ran existing benchmarks to validate performance improvements; results indicate enhanced performance without regressions.

Compatibility

• No migration concerns or backwards compatibility issues identified.
