Simplify StatsRewriteCtx rules by leveraging BoundExpressions

[robert3005]

Since we have BoundExpressions we don't have to go through the StatsRewriteCtx
to resolve the dtype anymore

Merging this PR will regress 1 benchmark

⚠️ Unknown Walltime execution environment detected

Using the Walltime instrument on standard Hosted Runners will lead to inconsistent data.

For the most accurate results, we recommend using CodSpeed Macro Runners: bare-metal machines fine-tuned for performance measurement consistency.

⚠️ Different runtime environments detected

Some benchmarks with significant performance changes were compared across different runtime environments,
which may affect the accuracy of the results.

Footnotes

1. 106 benchmarks were skipped, so the baseline results were used instead. If they were deleted from the codebase, click here and archive them to remove them from the performance reports. ↩

2. 4 benchmarks were run, but are now archived. If they were deleted in another branch, consider rebasing to remove them from the report. Instead if they were added back, click here to restore them. ↩

3. No successful run was found on develop (28f7cf0) during the generation of this report, so 0a128b6 was used instead as the comparison base. There might be some changes unrelated to this pull request in this report. ↩
