feat(webvitals): Updates performance score profiles with 0 weight components (#60517)

Adds 0 weight components to performance score profiles. This is needed
to ensure that the sum of all `avg(measurements.score.weight.*)` will
always equal 0. Also updates weights for each webvital to be consistent
across all profiles (this is possible now that we don't require weights
to add up to 1.00 in relay).
