[processing] Add a bunch of mixing field types to the {add field,field calculator} algorithms

PR Description:

Description

This PR adds a bunch of missing field types to processing's add field to the attributes table algorithm. Missing types goes from the most basic (boolean) to the widely adopted (datetime) and exciting ones (arrays).

Super, super helpful as part of models.

Edit: OK, this is a rabbit hole :) while doing this field type cleanup, noticed field calculator alg. also is missing a bunch of types. Fixed:

QGIS 4.0 TODO: harmonize the value ordering across those two algs (possibly through creating a field type parameter)
