RFR: 8287732: jdk/jshell/ToolEnablePreviewTest.java fails on x86_32 after JDK-8287496

[Aleksey Shipilev]

Manifests right now in x86_32 tier1 tests and GHA. The test tries to launch the tool via JDI/JVMTI, which does not fully work without continuations after [JDK-8287496](https://bugs.openjdk.java.net/browse/JDK-8287496):

I think test needs `@requires vm.continuations` as well.

Additional testing:
 - [x] Linux x86_32 `fastdebug`, affected test now skipped
 - [x] Linux x86_64 `fastdebug`, affected test still runs
