[DanielViberg]

• Working mult server compl
• Removed time measure prop
• Tweaked LspResolver to be server id dependent
• Fixed text complete server dependent
• Reset tests

Purpose: Volar 2 support

Note, should propbably be tested by more people before being merged to main!

Config

      "path": "vue-language-server",
      "args": ["--stdio"],
      "features": {

              "tsdk": "../node/v20.11.0/lib/node_modules/typescript/lib"
          }
      },
    },
    {
      "name": "ts-ls",
      "filetype": ["typescript", "javascript", "vue"],
      "path": "typescript-language-server",

          "plugins":[
            {
              "name": "@vue/typescript-plugin",
              "location":".../node/v20.11.0/lib/node_modules/@vue/typescript-plugin",
              "languages": ["vue"]
            }
          ]
      }
   }

Status:

• [x] completions
  • [x] auto imports
• [x] diagnostics
• [ ] definitions (working in some cases, but not all)
• [ ] references
