Add some more specific scopes for member access.

Add `meta.attribute.python` to mark otherwise non-special attributes.
Add `meta.indexed-name.python` to mark the name of the object being
indexed.

In combination with `meta.member.access.python` the above scopes can
help highlight member access that is no otherwise using a builtin or
some other special case. For highlighting method names in method calls
the combination of `meta.member.access.python` and
`meta.function-call.generic.python` could be used.

Fixes MagicStack#188.
