[Fix] (MG_Remote): CapsSnapshot.apiVersion carries the backend's own API version string, so a split client's GL_RENDERER names the real device instead of the target GL version (split build only; the pull build is unchanged, G1)

- PublishCapsSnapshot filled that field with info.RendererGLInfo.TargetGLVersion.toString(). The
  client reads it back through BackendObject_Remote::GetBackendAPIVersionString (CapsMirror's
  ApiVersion) and prints it in the parentheses of GL_RENDERER, which is the only place a real
  device is named; a monolith build fills the same parentheses from the backend's own
  GetBackendAPIVersionString. A split client therefore answered "Espryt (MobileGL Core) (4.6.0)"
  where monolith answered "Espryt (MobileGL Core) (Adreno (TM) 750, OpenGL ES 3.2)".
- The target version still crosses the wire inside the renderer-info blob (CapsCodec), which is
  where GL_VERSION reads it, so no reader loses it.
- Content only: the field already existed and the blob layout is untouched, so the wire
  fingerprint needs no bump, and the file compiles only under MOBILEGL_BUILD_DISAGGREGATED.
- Verified with a PC client against a phone server: Minecraft and Sodium both log
  "Espryt (MobileGL Core) (Adreno (TM) 750, OpenGL ES 3.2)".
