"fontversion" used to be modified to sort out fonts as a technique.
But that lost the original purpose to do the version control between
releases.
This change adds the dedicated property into the cache.

In some cases, non-English languages might appears first in current order.
and when having English name with non-English language ID like Google Noto CJK TC,
English name with English language ID will be dropped due to duplicate.
This fixes that issue.
Most of functionality should be moved to FcFreeTypeQueryAll()
for varfonts now though, if doing the same to FcFreeTypeQuery()
returns Null pattern because of inappropriate masking.
This might be not that big deal for varfonts support. but

The expression "1 << 31" will cause UBSAN to complain with this error message:
runtime error: left shift of 1 by 31 places cannot be represented in type 'int'
The same operation on unsigned types is fine, however. This CL replaces the
strings "1 <<" with "1U <<".
In 161c738 I switched from linear name scanning to binary searching.
That, however, ignored the fact that there might be more than one
name table entry for each pair we want to query.
To fix that and retain bsearch, I now get all name entries first,
sort them, and use for bsearching.
This fixes https://bugs.freedesktop.org/show_bug.cgi?id=105756
This makes scaning Voto Serif GX twice slower though, since we are
creating and sorting the list for each instance. In the next commit,
I'll share this list across different instances to fix this.
VotoSerifGX has over 500 named instances, which means it also has over a thousand
name table entries. So we were looking for names for over 500 pattern, looking for
some thirty different name-ids, and using linear search across the 1000 entries!
Makes scanning VotoSerifGX three times faster. The rest is probably the lang
matching, which can also be shared across named-instances. Upcoming.
This reverts commit 57764e3a36449da25bb829c34cb08c54e9e5de90.
For regular font pattern we don't look into fvar, so it doesn't make sense to
get non-variation from it either.
