[PATCH v2 07/21] config: document `read_early_config()` and `read_very_early_config()`

[Patrick Steinhardt <ps@pks.im>]

It's not clear what `read_early_config()` and `read_very_early_config()`
do differently compared to `repo_read_config()` from just looking at
their names. Document both of these in the header file to clarify their
intent.
