[MCP] Add configuration options to enable or disable specific tools (#5367)

Browse Source 
Some MCP servers expose a lot of tools. In those cases, it is reasonable
to allow/denylist tools for Codex to use so it doesn't get overwhelmed
with too many tools.

The new configuration options available in the `mcp_server` toml table
are:
* `enabled_tools`
* `disabled_tools`

Fixes #4796
