[LLDB][Test] Remove `skipIfWindows` for conditional breakpoint test (NFC)

[mib]

Summary

The test for conditional breakpoints on Windows was skipped because
there was no expression evaluation support at the time it was written.

After removing the annotation and testing it again, the test is passing.

LGTM. Please monitor the windows Buildbot to make sure it still passes after your commit though.
