2.9: native types: literal_eval all the things (#68938) (#69044)

* native types: literal_eval all the things (#68938)

With pallets/jinja#1190 merged our short-circuit
is no longer valid (has it ever been?) as now data like ' True ' may go
through our ansible_native_concat function as opposed to going through
intermediate call to Jinja2's native_concat before. Now we need to always
send data through literal_eval to ensure native types are returned.

(cherry picked from commit acdc9eb)

* Fix tests
