Resources: reject compressed content we can't decompress

This solution is composed of two features:

1) C++ code generated by RCC uses two symbols exported from QtCore that
are only present if the feature was compiled in. If the feature was not
compiled in, this will cause a linker error either at build time or at
load time (if they were functions, the error could be at runtime).

2) Binary files generated by RCC have a new header field containing
flags. We're currently using two flags, one for Zlib and one for
Zstandard.

This means we now have binary RCC format version 3.
