sparse-revlog: add a `trim_endidx` function in C
We are about to implement a native version of `slicechunktodensity`. For
clarity, we introduce the helper functions first.
This function implement a subpart of the python function `_trimchunk` in
`mercurial/revlogutils/deltas.py`. Handling of actual Python objects is left
to the caller function.

repo13 doesn't have any cached lfs files and its source never pushed its
files. Therefore, the files don't exist in the remote store. Use the files in
the user cache.

lfs -> normal -> lfs round trip conversions are possible. The 'none()'
predicate on the command line will override whatever is configured globally and
locally, and ensures everything converts to a regular file. For lfs -> normal,
there's no 'lfs' destination repo requirement. For normal -> lfs, there is.
