Vighnesh 906a00d498 Sync to upstream/release/655
* General
- Fix the benchmark require wrapper function to work in Lua
- Fix memory leak in the new Luau C API test

* New Solver
- Luau: type functions should be able to signal whether or not irreducibility is due to an error
- Do not generate extra expansion constraint for uninvoked user-defined type functions
- Print in a user-defined type function should be reported as an error
instead of logging to stdout
- Many e-graphs bugfixes and performance improvements
- Many general bugfixes and improvements to the new solver as a whole
- Fixed issue with Luau used-defined type functions not having all environments initialized
- Infer types of globals under new type solver

* Fragment Autocomplete
- Miscellaneous fixes to make interop with the old solver better

* Runtime
- Support disabling specific Luau built-in functions from being
fast-called or constant-evaluated
- Added constant folding for vector arithmetic
- Added constant propagation and type inference for Vector3 globals
