Revert "[FedCM] Allow button flow to replace widget flow"

This reverts commit a2783105732c27a57dd0c3e1100730cc4aec32e0.

Reason for revert: Suspected of causing failures on WebKit Linux Leak: https://ci.chromium.org/ui/p/chromium/builders/ci/WebKit%20Linux%20Leak/60801/overview (and other runs since)

Original change's description:
> [FedCM] Allow button flow to replace widget flow
>
> Since button flow implies stronger user login intention of, it should
> take precedence over the widget flow. In particular:
> 1. If there's an in-flight button request, reject any coming widget request
> 2. If there's an in-flight widget request, replace it with the button request
>
> This patch also fixes an issue where we persisted the rp_mode_ after a
> button flow.
