[jdk17u-dev] RFR: 8279011: JFR: JfrChunkWriter incorrectly handles int64_t chunk size as size_t

[Aleksey Shipilev]

Clean backport to fix JFR bug manifesting on 32-bit platforms. This PR would stay open a bit to get the change tested in mainline first.

Additional testing:
 - [x] Linux x86_64 fastdebug `jdk_jfr` (passes)
 - [x] Linux x86_32 fastdebug `jdk_jfr` (used to fail, now passes with 1 unrelated failure)
