Windows support in pg_import_system_collations
Windows can enumerate the locales that are either installed or
supported by calling EnumSystemLocalesEx(), similar to what is already
done in the READ_LOCALE_A_OUTPUT switch. We can refactor some of the
logic already used in that switch into a new function
create_collation_from_locale().
The enumerated locales have BCP 47 shape, that is with a hyphen
between language and territory, instead of POSIX's underscore. The
created collations will retain the BCP 47 shape, but we will also
create a POSIX alias, so xx-YY will have an xx_YY alias.
A new test collate.windows.win1252 is added that is like
collate.linux.utf8.
