script: Re-implement evaluate_key_path_on_value in IndexedDB (#38847)

The current implementation of evaluate_key_path_on_value was translated
from gecko, and it is incomplete. The unimplemented part occurs many
crashes in WPT tests.

This PR re-implements it according to the spec. It should eliminate many
crashed WPT tests, and increase the code readability.

Testing: Update WPT test expectation
Fixes: #38817 partially, and #25325
