Sync to upstream/release/637 (#1354) 
# What's Changed?

- Code refactoring with a new clang-format
- More bug fixes / test case fixes in the new solver

## New Solver

- More precise telemetry collection of `any` types
- Simplification of two completely disjoint tables combines them into a
single table that inherits all properties / indexers
- Refining a `never & <anything>` does not produce type family types nor
constraints
- Silence "inference failed to complete" error when it is the only error
reported
