The first call to persisting facts would work due to the assignment of a
MutableMapping calling __setitem__ but subsequent module fact data would
not be propogated to the fact cache plugins because update() doesn't
invoke __setitem__. This changes the behavior a little bit and ensures
set() is called on cache plugins.
Also does some reorganization/cleanup on the magic vars/delegated
variable generation portions of VariableManager to make the above
possible.
Fixes#12633
Due to the way we're now calculating delegate_to, if that value is based
on a loop variable ('item') we need to calculate all of the possible
delegated_to variables for that loop.
Fixes#12499
Follow up to 8769f03c, which allows the undefined var error to be raised
if we're getting vars with a full context (play/host/task) and the host
has already gathered facts. In this way, vars_files containing variables
that fail to be templated are not silently ignored.
Now, instead of relying on hostvars on the executor side, we compile
the vars for the delegated to host in a special internal variable and
have the PlayContext object look for things there when applying task/
var overrides, which is much cleaner and takes advantage of the code
already dealing with all of the magic variable variations.

These used to go in vars_cache, so merging them in after that as they
are "live" variables and the user would most likely want to see these
above anything else.
Required some rewiring in inventory code to make sure we're using
the DataLoader class for some data file operations, which makes mocking
them much easier.
Also identified two corner cases not currently handled by the code, related
to inventory variable sources and which one "wins". Also noticed we weren't
properly merging variables from multiple group/host_var file locations
(inventory directory vs. playbook directory locations) so fixed as well.
* Fixes hostvar serialization issue (#12005)
* Fixes regression in include_vars from within a role (#9498), where
we had the precedence order for vars_cache (include_vars, set_fact)
incorrectly before role vars.
* Fixes another bug in which vars loaded from files in the format of
a list instead of dictionary would cause a failure.
