[jdk17u-dev] RFR: 8283298: Make CodeCacheSegmentSize a product flag [v2]

[Dmitry Chuyko]

> As suggested in https://github.com/openjdk/jdk17u-dev/pull/753 this change can be backported separately. I am going to update that JDK-8284578 PR on top on this one.
> The patch is almost identical to the original one but the single change in test is excluded. Test part would otherwise be exactly reverted by necessary JDK-8283229 but the test file is not present in jdk17u as JDK-8281467 (Allow larger OptoLoopAlignment and CodeEntryAlignment) is missing. The latter can be backported after this one if necessary.
> 
> Testing: tier1, tier2 on x86 and aarch64.
