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

Luau

Luau is a fast, small, safe and gradually typed embeddable scripting language derived from Lua. It is used by Roblox game developers to write game code, as well as by Roblox engineers to implement large parts of the user-facing application code as well as portions of the editor (Roblox Studio) as plugins.

This repository hosts documentation for the language as well as satellite materials.
