### What problem does this PR solve?
When multiple MCP servers expose tools with the same name, the agent
currently registers those tools using their original MCP names. This can
lead to two issues:
- later MCP tools may overwrite earlier ones in the agent tool map
- duplicate function names may be exposed to the LLM
This PR fixes duplicate MCP tool-name handling by applying the same
indexed naming strategy already used for native agent tools. Native
tools are exposed with generated names such as `<tool_name>_<index>` to
avoid collisions, and MCP tools now follow the same convention for
consistency.
Specifically, this PR:
- assigns unique indexed function names to MCP tools exposed to the LLM
- preserves each MCP tool's original server-side name in an
`MCPToolBinding`
- dispatches MCP calls using the original MCP tool name while keeping
the indexed name in the agent tool map
- allows MCP metadata conversion to override only the OpenAI function
name without modifying the original MCP tool metadata

### Validation
The validation was performed using two MCP servers. Both servers exposed
a tool with the same name: `mcp0`. Both tools take no input parameters.
**MCP Server One:**

**MCP Server Two:**

/>
**Before the fix:**
When invoking `mcp0`, only the `mcp0` tool from the MCP server injected
later could be called successfully. As shown below, both `mcp0` tools
were present, but only the later-registered one was actually invokable.

/>
**After the fix:**
Both `mcp0` tools can now be invoked correctly.
