Also fixes a bug where we were passing an incorrect number of parameters to
_do_handler_run() when processing an include file in a handler task/block.
Fixes#13560
Otherwise, each relative include path is checked on its own, rather
than in relation to the (possibly relative) path of its parent, meaning
includes multiple level deep may fail to find the correct (or any) file.
Fixes#13472
Previously, we were filtering the task list on tags for each host
that was including the file, based on the idea that the variables
had to include the host information. However, the top level task
filtering is play-context only, which should also apply to the
included tasks. Tags cannot and should not be based on hostvars.
prior to this commit, an attempt to use the `include:` directive would
fail in a `rescue:` or `always:` block if there were failures in the
main block task list.
Resolves#12876.
