Preserve prompt message structure through vMCP relay (#4334)

The vMCP prompt relay flattened all backend messages into a single
string with "[role] text\n" format, discarding non-text content and
individual message roles. The handler then wrapped this flat string
as a single "assistant" message, losing the original conversation
structure.

Replace the lossy ConvertPromptMessages with structured
ConvertMCPPromptMessages/ToMCPPromptMessages that preserve individual
messages with their original roles and full content types (text, image,
audio, embedded resource, resource link). This removes the documented
"Phase 1 limitation" for prompt message handling.
