[jdk25u-dev] RFR: 8368159: Significant performance overhead when started with jdwp agent and unattached debugger

[Roland Mesde]

Backporting JDK-8368159: Significant performance overhead when started with jdwp agent and unattached debugger.

This commit replaces the imprecise can_post_frame_pop() check with new has_frame_pops(JavaThread* thread) function for accurate detection of when JVMTI cleanup is actually needed.

Ran related tests (passed) on linux-x64, linux-aarch64, macos-aarch64 and windows-x64:

(Passed) - make test TEST=test/hotspot/jtreg/serviceability/jvmti

Results are attached.
