8316179: Use consistent naming for lightweight locking in MacroAssembler

[shipilev]

Clean backport to make subsequent backports clean. The risk is low, as it only renames things. There might still be build failures due to missing renames, but that should be easily caught.

Additional testing:

• macos-aarch64-server-fastdebug, hotspot:tier1
