There are multiple sites in "pack-bitmap-write.c" where we use the global `the_repository` variable, either explicitly or implicitly by using `the_hash_algo`.
Refactor the code so that the `struct bitmap_writer` stores the repository it is getting initialized with. Like this, we can adapt callsites that use `the_repository` to instead use the repository provided by the writer.
Remove the `USE_THE_REPOSITORY_VARIABLE` define.
