Subject: Add a stub recovery UI.

This allows recovery to work on devices without screen.
The stub recovery UI does nothing except print to stdout.

Test: write 'recovery\n--wipe_data\n--reason=wipe_data_from_ota\n'
      to misc and boot to recovery on a device without screen.
Bug: 33175036

Subject: recovery: Fix the broken UI text.

UI text is broken (doesn't show any text during FDR) due to commit
d530449e54bd327e9c26209ffa0490c6508afe6c, which reordered the calls to
RecoveryUI::SetLocale() and RecoveryUI::Init().

Because Init() uses the locale info to load the localized texts (from
images), the locale must be set prior to that via SetLocale(). This CL
refactors Init() to take the locale parameter, and removes the odd
SetLocale() API.

Bug: 34029338
Test: 'Run graphics test' under recovery.
