[Not Merge] POC on async linter with linter rule using AI

[RodgeFu]

The change in the PR mainly contains 3 parts:

1. change to compiler to support async linter, optimize getSignatureHelp and provide LmProvider
2. change to vscode extension to support custom request for server to call to provide AI capability
3. A sample linter lib 'azure-linter' providing: (not a good name, just a sample lib to demo linter rules using AI)
   • A framework to use AI easily in linter rule which will also help to aggregate AI requests in batch to reduce the potential perf impact. If you are interested,
     • Refer to https://github.com/RodgeFu/typespec/blob/8f911701e91a6b77e0d6a09d88016637353a4982/packages/azure-linter/src/rules/duration-with-unit.naming.csharp.rule.ts#L32 for a simple sample code of linter rule using AI.
     • Refer to https://github.com/RodgeFu/typespec/blob/8f911701e91a6b77e0d6a09d88016637353a4982/packages/azure-linter/src/lm/lm-rule-checker.ts#L20 for how AI requests are aggreagated.
   • 3 sample linter rules
     • csharp.naming.duration-with-unit
     • csharp.naming.boolean-property-starts-with-verb
     • csharp.naming.avoid-too-generic-name (this is simulating a "bad" linter rule which will check hundreds of properties and see how things going on in this case. We should avoid this kind of linter rule in real usage)

How to try it:

1. install the compiler
2. install the linter lib
3. install the vscode extension
4. Update tspconfig.yaml to include the linter rule like below

linter:
  enable:
    "azure-linter/csharp.naming.boolean-property-starts-with-verb": true
    "azure-linter/csharp.naming.duration-with-unit": true
    "azure-linter/csharp.naming.avoid-too-generic-name": false

** This PR/branch is for trying the impact from async linter rule. Not expected to be merged. If things go well, I will file separated PRs for different feature areas to review and merge.
