HPCC-10952 Add AuthenticateFeature 'FileUploadAccess' to env setting

The 'FileUploadAccess' permission is missing from the "Esp Features
for SMC". In this fix, the AuthenticateFeature 'FileUploadAccess' is
added to environment.xml. When ECLwatch is started, CLdapSecManager::
createFeatureMap() reads the 'FileUploadAccess' from esp.xml and adds
the permission into LDAP server.
