[Docs] Document GLM-4.7 tool parser

[zcxGGmu]

Motivation

Issues #4400 and #4329 ask how to configure GLM-4.7 tool-calling options in LMDeploy. Current main includes the glm47 tool parser, but the tool-calling docs only list internlm, qwen, and llama3 parser names.

Refs #4400
Refs #4329

Modification

• Add GLM-4.7 to the English and Chinese tool-calling docs.
• List glm47 as a supported --tool-call-parser name.
• Add a minimal GLM-4.7 launch example using --tool-call-parser glm47.

BC-breaking (Optional)

No. Documentation only.

Use cases (Optional)

lmdeploy serve api_server /path/to/GLM-4.7-Flash --tool-call-parser glm47
