CMake 3.18 introduced the file(ARCHIVE_CREATE) API that we use with
COMPRESSION Zstd for compressing corelib's mimedatabase.
It's possible to build CMake without proper zstd support, and we have
encountered such builds in the wild where the file(ARCHIVE_CREATE) call
crashes.
Add a configure test to determine whether CMake properly supports the
Zstd compression method.
