Process all the fields in top level request object even if it contain…

…s request body (#2155)

## Changes

When regenerating CLI with a new Go SDK
#2126 I've noticed that some
parameters such as `no_compute` for apps are not added as flags for the
CLI commands.

This happened because we ignored all other top level fields if there's a
request body object field.

This PR relies on new AllFields method from Genkit which returns fields
from both request object and request body object.
