RFR: 8253372: [TESTBUG] update tests which require jvmti - hotspot

[Alex Menkov]

This is subtask which covers test in hotspot/jtreg except test/hotspot/jtreg/vmTestbase/nsk/jvmti (there is a separate
issue for it: JDK-8253371)

In most tests just "@requires vm.jvmti" is added,
in several test '@requires vm.flavor != "minimal"' is removed (when this requirement is only to ensure test VM has
JVMTI included)
