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

[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.
