feat(report/metrics): adds experimental stats

[sverweij]

Description

• adds the newly introduced (experimental) stats to the output of the metrics reporter
• refactors the metric reporter (so it's easier to provide other output formats later on)
• formats all the numbers with Intl - which is particularly useful for the size stat as that tends to run in the thousands.

Motivation and Context

Might prove useful

How Has This Been Tested?

• green ci
• updated & added automated non-regression tests
