[jdk13u-dev] RFR: 8243452: JFR: Could not create chunk in repository with over 200 recordings

[Ekaterina Vergizova]

I'd like to backport JDK-8243452 to 13u for parity with 11u.
The patch doesn't apply cleanly due to context difference in jdk/jfr/internal/RepositoryChunk.java (JDK-8244463 is not in 13u), reapplied manually.
Tested with tier1 and jdk/jfr tests; the test attached to the issue fails without the patch, passes with it.
