RFR: 8360641: TestCompilerCounts fails after 8354727 [v2]

[Manuel Hässig]

> After integrating #25872 the calculation of the`CICompilerCount` ergonomic became dependent on the size of `NonNMethodCodeHeapSize`, which itself is an ergonomic based on the available memory. Thus, depending on the system, the test `compiler/arguments/TestCompilerCounts.java` failed, i.e. locally this failed, but not on CI servers.
> 
> This PR changes the test to reflect the changes introduced in #25872.
> 
> Testing:
>  - [ ] [Github Actions](https://github.com/mhaessig/jdk/actions/runs/15932906313)
>  - [x] tier1,tier2 plus Oracle internal testing
