Support for xmake.lua

[wujilingfeng]

Xmake.lua is a domain-specific language (DSL) based on Lua. Currently, there is no available language server protocol (LSP) for it. Currently, the most serious issue is that zed automatically handles indentation when I save files, resulting in syntax errors. If extension support for xmake.lua cannot be provided, please ask zed to turn off the automatic indentation feature when zed processes xmake.lua

There is now an LSP in progress at https://github.com/CppCXY/xmake_ls. It is based on the EmmyLua LSP.
