core(performance): hide most audits under passing conditions

[adamraine]

Closes #16265

Several performance audits follow a pattern where they mark themselves as informative when there isn't a problem, instead of going into a true passing state (i.e. hidden in the "Passed audits" section). Although this pattern is necessary to keep audits like largest-contentful-paint-element visible, it's kinda overused which has led to some confusion as mentioned in #16265.

This PR removes the "informative on pass" pattern from most audits. The following audits will still use the "informative on pass" pattern because they contain critical information for CWV:

• largest-contentful-paint-element
• layout-shifts
• work-during-interaction

Might be worth keeping the "informative on pass" pattern for third-party-summary since 3P payloads could still be high even in a passing state, but that's debatable.
