[M144-LTS][ganesh] Use & when testing for input attachment self-dep

Other than these two sites, kForInputAttachment and
kForNonCoherentAdvBlend are not treated as mutually exclusive.

When using only == kForInputAttachment, the layout and bindings wouldn't
apply correctly for a renderpass that was using both forms of self
dependencies.
