[FIX] ir_model: ignore monetary fields during install (#21789)

Previous to this commit, we try to load as many fields as possible
during module installation, however sometimes some fields are not ready
to be loaded, which is the case for custom monetary fields, thus when
trying to find the current model's currency_id field it would not find
it at all, generating an assertion error.

This commit changes this by completely skipping monetary fields if they
are not ready to be loaded.
