  Log Message:
  -----------
  [lldb] Add MCP tools to create and destroy debugger instances (#209288)

Add debugger_create and debugger_delete tools to the MCP server so a
client can manage debugger instances, not just command the ones that
already exist. debugger_create detaches the new debugger's stdio from
the host process (redirecting input/output/error to the null device) so
its prompt and asynchronous output cannot corrupt an MCP stream that
shares the host's stdout. Command results flow through
CommandReturnObject and are unaffected.

Factor the tool and resource registration out of
ProtocolServerMCP::Extend into a shared PopulateServer() so an embedded
in-process server (e.g. in lldb-mcp) can install the same set.
