ci: force frame pointers for Codspeed

[myrrc]

As RUSTFLAGS were overriding rustflags from config, Codspeed runs were built without mold and
frame pointers

⚠️ 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. 176 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. 1 benchmark was run, but is now archived. If it was deleted in another branch, consider rebasing to remove it from the report. Instead if it was added back, click here to restore it. ↩

3. No successful run was found on develop (e38405d) during the generation of this report, so 9a6d34a was used instead as the comparison base. There might be some changes unrelated to this pull request in this report. ↩

We're doing this already in the cargo config.

[myrrc]

@0ax1 That's the case, RUSTFLAGS were overriding this setting so it wasn't propagated.
