[ADD] file-not-used: pylint-odoo 6.0.x had this lint but was missed in the migration to pre-commit-hooks

Related to OCA/pylint-odoo#393

The check file-not-used:

• https://github.com/OCA/pylint-odoo/blob/3f866d53b5abb8a3ebbad7ca07aa81751b136752/pylint_odoo/checkers/modules_odoo.py#L1062C16-L1074

Should be migrated to odoo-pre-commit-hooks

But I think we only missed to migrated it

So, we need to start this migration now

Also, notice the new files neutralize.sql now are auto-detected from odoo:

• https://github.com/odoo/odoo/blob/e5dbded9bb363351feff7ca8a56c7f8a6860f492/odoo/modules/neutralize.py#L18

And we need to add a new way to add excepted files (Maybe using the same way than pre-commit configuration uses)

Please, check what other checks we missed from issue OCA/pylint-odoo#393
Please, check what other files are auto-detected from odoo too

Hooks here already have a config file, so we can add a key like file-not-used-whitelist that will exclude said files from creating errors. 🤔

I propose the following course of action for this issue:

1. Use the config file oca_hooks.cfg to add a new parameter which states which files to ignore for this message
2. While we are at it, add a new python file base_checker which holds data common to all checkers:
   1. enable/disabled messages
   2. module name
   3. manifest path
      This will be a minimal changes refactor just to plant the inheritance seed, it will also help tackle Add parameter, config, environment variable for pamaters of checks #39 by automatically giving config access to all checkers that inherit base_checker.

As for migrating the actual message, I think instead of doing it the old way we can just use a glob and we could also lint for not used static files now that they must be included in the assets section of the manifst file.
