[llvm] [llvm][test][CGPluginTest] Fix missing `plugins` in test requirements (PR #215010)

[Seth Junot via llvm-commits]

https://github.com/xSetech created https://github.com/llvm/llvm-project/pull/215010

CGTestPlugin.so is only built when LLVM_ENABLE_PLUGINS is ON, so under this configuration the test will still run but without llc able to load the plugin and emit the expected message:
- LLVM_LINK_LLVM_DYLIB=ON (`llvm-dylib` set)
- LLVM_ENABLE_PLUGINS=OFF (`plugins` unset)

This changes the test so that it's only run when CGTestPlugin.so would have been built and is marked unsupported otherwise.

under this configuration the test will still run but without llc
able to load the plugin and emit the expected message:
- LLVM_LINK_LLVM_DYLIB=ON (`llvm-dylib` set)
- LLVM_ENABLE_PLUGINS=OFF (`plugins` unset)

This changes the test so that it's only run when CGTestPlugin.so would
