Solve BiDi problem when phone number is concatenated with RTL-string

Solves BiDi problem that might cause phone number to be displayed
incorrectly in the dialer. Issue might occur when a phone number
is concatenated with a custom number label containing an RTL-string.

Solved by changing affected labels from TextView to BidiTextView.

Removed function spanDisplayNumber in BottomRow which are now obsolete.

Updates the DialerBidiFormatter to prevent whitespace to be misplaced
within a BidiTextView.
