Fixed HDFFV-10214:
* Updated comments in the library to accurately reflect the semantics of the H5FD_FEAT_POSIX_COMPAT_HANDLE flag. * Removed the check for the POSIX compatible handle feature flag when determining if a VFD supports SWMR. Partial work for HDFFV-10197: * Added a new H5FD_FEAT_DEFAULT_VFD_COMPATIBLE feature flag that is set when a VFD creates output that is compatible with the default VFD. Will be used in the testing but might also be generally useful to users.
