reftable: remove name checks

Browse Source 
In the preceding commit we have disabled name checks in the "reftable"
backend. These checks were responsible for verifying multiple things
when writing records to the reftable stack:

  - Detecting file/directory conflicts. Starting with the preceding
    commits this is now handled by the reftable backend itself via
    `refs_verify_refname_available()`.

  - Validating refnames. This is handled by `check_refname_format()` in
    the generic ref transacton layer.

The code in the reftable library is thus not used anymore and likely to
bitrot over time. Remove it.
