Generalise use of `{pred T}` from coq/coq#9995
Use `{pred T}` systematically for generic _collective_ boolean
predicate.
Use `PredType` to construct `predType` instances.
Instrument core `ssreflect` files to replicate these and other new
features introduces by coq/coq#9555 (`nonPropType` interface,
`simpl_rel` that simplifies with `inE`).
