Always suppress font error during resource loading

I suppressed the font error during resource loading only if the
targetSdkVersion is API 28 or before, but it turned out that this
makes developers hard to use font resources since:
- We don't give a list of supported font files and OEM may extend/shrink
  the font support.
- There is no way to resolve this error during layout inflation.

So, now always supress the IllegalArgumentException during building
Typeface in resource loading.
