Downgrade error in object_aclmask_ext() to internal
The "does not exist" error in object_aclmask_ext() was written as
ereport(), suggesting that it is user-facing. This is problematic:
get_object_class_descr() is meant to be for internal errors only and
does not support translation.
For the has_xxx_privilege functions, the error has not been
user-facing since commit 403ac226ddd. The remaining users are
pg_database_size() and pg_tablespace_size(). The call stack here is
pretty deep and this dependency is not obvious. Here we can put in an
explicit existence check with a bespoke error message early in the
function.
Then we can downgrade the error in object_aclmask_ext() to a normal
"cache lookup failed" internal error.
