Add PR and Release benchmark with new changes in framework

[roshkhatri]

This adds the workflow improvements for PR and Release benchmark where it runs on 'c8g.metal-48xlforARM64andc7i.metal-48xlforX86`

PR benchmarking will be executed on ARM64 machine as it has been seen to be more consistent. Additionally, it runs 5 iterations for each tests and posts the average and other statistical metrics like

• CI99%: 99% Confidence Interval - range where the true population mean is likely to fall
• PI99%: 99% Prediction Interval - range where a single future observation is likely to fall
• CV: Coefficient of Variation - relative variability (σ/μ × 100%)

Note: Values with (n=X, σ=Y, CV=Z%, CI99%=±W%, PI99%=±V%) indicate averages from X runs with standard deviation Y, coefficient of variation Z%, 99% confidence interval margin of error ±W% of the mean, and 99% prediction interval margin of error ±V% of the mean. CI bounds [A, B] and PI bounds [C, D] show the actual interval ranges.

For comparing between versions, it adds a workflow which runs on both ARM64 and X86 machine. It will also post the comparison between the versions like this: https://github.com/valkey-io/valkey/issues/2580#issuecomment-3399539615

@roshkhatri looks like we are adding x86 as well? I am not sure if we should add x86 runs if we are not confident on the stability and numbers yet.

Yes, we would still like to get the benchmark numbers for X86, while doing the releases. The PR only used ARM64 though
