Issue #9080: Checking for available libheif codecs at compile-time. 

From libheif >= 1.14.0, the pkg-config variable will become bogus and always
return 'yes' so we now need to check for codec avaibility at compile time the
same way we look for these at runtime.

It may seem irrelevant to do these checks since these codecs can be added
anytime later, but it's still very good information for packagers to immediately
see that we have runtime package missing.
