Theme Customizer: Validate themes with more than just an existence check.

* The current theme goes through validate_current_theme().
 * If doing a preview of a different theme, we check theme->errors().

Also:
 * Don't attach previewing hooks when previewing the current theme.
Aside from being unnecessary, this prevents issues with a theme with
the error of theme_parent_invalid.
 * Call send_origin_headers() earlier, to allow wp_die( '0' ) to properly
be returned in a domain mapping situation.
 * Fix the 'Save & Activate' message on themes.php.

fixes #20921.
