TypeSpec Validation Experience Improvements

Opening an issue on items I think could be done to improve the TypeSpec Validation CI/local run

### CI only
- Buffer the output so the collpased group can directly show if it succeeded or failed

Instead produce something like
- ✔️ Validating specification/compute/Compute.Management
- ❌ Validating specification/compute/Disk.Management
- ✔️ Validating specification/compute/Gallery.Management
- ✔️ Validating specification/compute/Sku.Management

- Run git diff with colors [Example](https://github.com/Azure/typespec-azure/blob/cfb35e54dd5ea9ea35e13ddc8bf2972ffbc1515b/.github/workflows/external-integration.yml#L81)

### Tool
- Summary of which rule failed at the end/less noise
- Related to that see if each rule can be run with `ora` or something like that that will keep it nice and grouped with status check
- For rules with sub rules like tspconfig validation would be nice to format those like typespec errors/warnings with colors

hard to see from this which are are actually blocking, something like this could be nice

combined with a custom problem matcher each error coudl show up in the right place directly in tspconfig.yaml in the pr review
