cache.h: create 'index_name_pos_sparse()'
Add 'index_name_pos_sparse()', which behaves the same as 'index_name_pos()',
except that it does not expand a sparse index to search for an entry inside
a sparse directory.
'index_entry_exists()' was originally implemented in 20ec2d034c (reset: make
sparse-aware (except --mixed), 2021-11-29) as an alternative to
'index_name_pos()' to allow callers to search for an index entry without
expanding a sparse index. However, that particular use case only required
knowing whether the requested entry existed, so 'index_entry_exists()' does
not return the index positioning information provided by 'index_name_pos()'.
This patch implements 'index_name_pos_sparse()' to accommodate callers that
need the positioning information of 'index_name_pos()', but do not want to
expand the index.
