tags-cache: directly perform a monimal walk for hgtagsfnodescache warming

We do something narrower than the path retrieving data. So lets use dedicated
code instead.

This provides further useful speedup:

### data-env-vars.name            = mozilla-try-2023-03-22-zstd-sparse-revlog
  # benchmark.name                = hg.debug.debug-update-cache
  # bin-env-vars.hg.flavor        = default
  # bin-env-vars.hg.py-re2-module = default
  # benchmark.variants.pre-state  = warm
