[OE-Core][PATCH v2 3/5] oeqa/utils/postactions: isolate directory creation in dedicated action

["Alexis Lothoré" <alexis.lothore@bootlin.com>]

From: Alexis Lothoré <alexis.lothore@bootlin.com>

In order to be able to create actions that could store new files during
failed test post actions, we need to split artifacts directory creation
from artifacts retrieval.

Create a new dedicated action to create artifacts main directory so we can
add actions creating files in this new directory, without worrying about
actions order if at least this action is set first.

Signed-off-by: Alexis Lothoré <alexis.lothore@bootlin.com>

Changes in v2:
- use new shared helper get_json_result_dir()
