[Android] Show simplified pages in a full tab instead of Custom Tabs

[SergeyZhukovsky]

Description

Brave opens simplified pages in Custom Tabs instead of full tabs. It's not very convenient as there is no way to switch tabs but only by closing the current simplified page.

Steps to reproduce

1. Go to Settings->Accessibility and enable Simplified view for web pages
2. Visit some web sites that support it, some wikipedia articles are good candidates.
3. Click Show simiplified view on the bottom when it appears.

Actual result

A web page opens in a Custom Tab, no way to switch tabs there.

Expected result

A web page opens in a full tab.
