Add hinted version of Tibetan Bold v1.00.

Note: These were run through ttx by autofix. TTX builds more compact
tables than what were in the drops and what was previously in the
repo.  The ttx decompilation is the same except for the autofix
modifications (vendor url in name table, ulUnicodeRanges in os/2
table).  This accounts for the significant size differences in some
tables in the existing Tibetan fonts, there are no functional
differences except for the two small autofix changes.
