Replace all tag inputs with the accessible tag input from EUI

[aphelionz]

Anywhere a legacy tag input exists, it should be replaced with the far more accessible version of the tags input from EUI, wherever possible

@elastic/kibana-design is it still an EUI issue?

[cchaos]

EUI has a EuiComboBox component that can replace these and is accessible. Replacement will need to be done by an engineer though.

Thanks @cchaos,
@elastic/kibana-management not sure if you are aware but there is an EUI component that can solve this issue

Cool thx for the heads up @AlonaNadler .

I don't know of anywhere left with the legacy tag input though, if one exists, this issue will naturally disappear with our continued EUI-ification and don't think this needs to be tracked separately.
