Subject: [PATCH 1/2] kunit: tool: move Kconfig read_from_file/parse_from_string
to package-level
read_from_file() clears its `self` Kconfig object and parses a config
file.
It is a way to construct Kconfig objects more so than an operation on
Kconfig objects. This is reflected in the fact its only ever used as:
kconfig = kunit_config.Kconfig()
kconfig.read_from_file(path)
So clean this up and simplify callers by replacing it with
kconfig = kunit_config.parse_file(path)
Do the same thing for the related parse_from_string() function as well.
