vcomp/lavc: print codec supp pixfmts with LL_INFO

print the codec supported formats always (normally)

By default, most of the output is in VERBOSE except the the finally
selected pixfmt. At least this information displayed by default may be
useful (eg. to point out if/that suboptimal pixfmt is used).
