8275162: Replace 'def' macros in mutexLocker.cpp

[coleenp]

This patch removes the 'def' macros from mutexLocker.cpp so it can use the default values for _allow_vm_block when possible and no more macro.
Tested with tier1-3 with product and debug builds.

+1 for getting rid of the x-macros when possible. Personally, I'm willing to pay the price of having the name duplication, given how the code becomes easier to understand and more IDE friendly.

This change depended on the change for JDK-8274794 which I'm not going to redo. Will try Ioi's varargs idea.
