[Android] New UI for send tab to self

Chromium change:
https://github.com/chromium/chromium/commit/8f81d7723f510c99bb651770b6d731d2fdf486c1

[send-tab-to-self/android] Add account UI to "no target devices" sheet
Behavior changes are behind a feature flag disabled by default.
This footer was already present in the device picker, now it's present
on the "no target devices" UI too.
Mock is "Option 2" here: https://docs.google.com/presentation/d/1w4me9wINwMW2UD-uuSQGMKiWuqkX9GDfAFvSM74Pt00/edit#slide=id.ge2c74ccf3a_0_4
