RFR(S): 8164737 - Remove Unsafe dependency from ProcessTools

[Christian Tornqvist]

Hi everyone,

 

Please review this small change that removes the unnecessary dependency on
Unsafe from ProcessTools. Jdk.test.lib.ProcessTools use some methods from
jdk.test.lib.Utils which has the getUnsafe() method, all tests that use
ProcessTools needed to have the @modules java.base/jdk.internal.misc even if
they don't use Unsafe. 

 

This change moves getUnsafe() into a new class:
jdk.test.lib.unsafe.UnsafeHelper and updates the few existing tests that use
Unsafe to use this class instead.
