 Implement RFC 157

 This adds a new overload of MgMap::Create that accepts:

  - map definition id
  - map name
  - image width
  - image height
  - view center X
  - view center Y
  - view scale
  - dpi

 With this overload, the created MgMap instance can be used on the
 following APIs statelessly without needing to open it first from a session
 repository (via a session id and map name pair)

  - MgRenderingService::QueryFeatures
  - MgRenderingService::QueryFeatureProperties
  - MgRenderingService::RenderMapLegend
  - MgRenderingService::RenderDynamicOverlay

 With this change, there is enough APIs in place from which to build a
 stateless map viewer that can perform selections and does not require
 creating or interacting with a session repository or resources inside it.

 As an addendum to the original RFC, the MgSelectionBase::SetMap method has
 also been promoted to EXTERNAL_API to allow selections from an
 MgFeatureInformation to be interrogated without throwing.

 A server unit test has been added to verify these new MgMap::Create
 parameters stick on the map.

 A series of .net unit tests have been added to exercise the aforementioned
 rendering service APIs using the statelessly-created MgMap.

 Fixes #2766
