RFR: 8254913: Increase InlineSmallCode default from 2000 to 2500 for x64

[Eric Caspole]

We have seen some specific benefits to increasing InlineSmallCode to 2500 from 2000, and across the whole promo build
perf test collection the change is neutral to slightly positive, where the tests are run on modern OCI systems.

Passed tier1 testing, some ad-hoc perf testing and more compiler related parts of the weekly promo performance set.

Thanks,
Eric
