Replace Lohit Devanagari/Tamil fonts with Droid versions.

WebView's fallback lists previously provided only regular weight for Tamil,
so I adapted Hebrew's separate Regular/Bold logic there. Also of note is
that while the rest of the system uses the UI Tamil fonts, WebView
substitutes the non-UI version.

The Devanagari font needs to fit on all devices, so we only supply a
single font there.
