Previously we disallowed use of arbitrary properties on INTERFACE libraries. The goal was to future-proof projects using them by not allowing properties to be set that may affect their future inclusion in the generated buildsystem. In order to prepare to actually include INTERFACE libraries in the generated buildsystem, drop the filter and allow arbitrary properties to be set. Issue: #19145
