Set screenshot smart actions to be enabled by default

Screenshot smart action are shipping in QPR2. We have 2 flags for
the feature, one in sysui code and one in AiAi. For QPR2, the value
for both of these flags in Java is `false` and we will use the flags
to rollout the feature safely. For R, we would like the feature to
be enabled by default in Java. We will still keep the flags in place
so we can use them as an escape hatch if the feature needs to be
disabled for some reason.

Bug: 148566220
Test: Manual (took a screenshot of a boarding pass and confirmed that
the smart action is shown)
