Vighnesh-V 77295c3610
Sync to upstream/release/647 (#1469)
# General Updates
Fix an old solver crash that occurs in the presence of cyclic
`requires()`

## New Solver
- Improvements to Luau user-defined type function library
- Avoid asserting on unexpected metatable types
- Properties in user defined type functions should have a consistent
iteration order - in this case it is insertion ordering

# Runtime
- Track VM allocations for telemetry
