hash: drop (mostly) unused `is_empty_{blob,tree}_sha1()` functions

The functions `is_empty_{blob,tree}_sha1()` are mostly unused, except for a single callsite in "read-cache.c". Most callsites have long since been converted to use the equivalents that accept a `struct object_id` instead of a string. Adapt the remaining callsite and drop those functions.
