RFC 2251 section 4.6 forbids deleting individual values of attributes without an equality matching rule. Collect remaining values with REPLACE instead of REMOVE-by-value. Closes spring-projectsgh-1263 Signed-off-by: arimu1 <19286898+arimu1@users.noreply.github.com>

DirContextAdapter.getModificationItems()used REMOVE-by-value for partial updates of multi-valued attributes. That fails on strict directories (for example OpenLDAP) for types without an equality matching rule such asfacsimileTelephoneNumber(RFC 4519). RFC 2251 section 4.6 requires REPLACE of remaining values instead.NameAwareAttributenow records whether equality matching is defined (RFC 4519 types without it, plus an explicit constructor). Ordered attributes and types without equality matching are replaced in full; attributes with equality matching keep per-value ADD/REMOVE.Summary
Fixes #1263
Closes gh-1263
