Sync to upstream/release/670 (#1779)
# General 
This week has been focused primarily on bugfixes, with a ton of
usability improvements to the new solver, fragment autocomplete, and the
concrete syntax tree project.

## Runtime
- Fix an assertion caused by failing to allocate native code pages.
- Expose a `lua_pushrequire` function, which performs the same
initialization steps as `luaopen_require` but does not register require
globally. This lets users create specialized, custom `requires`.

# New Solver
- Fix a bug in simplification of types caused by combinatorial explosion
of intersection and union types.
- Fix a memory leak in fragment autocomplete
- Improve the isolation of modules in fragment autocomplete
- Throw errors when users define a type function with the name `typeof`
- Continue to narrow intersection types which might be `never`.
- Major rework of generalization continues - we are blazing a new path
with eager + non-reentrant generalization and actively working to make
these more performant and less error prone.
- Improve the ability of `and/or` type functions to reduce, even when
their arguments are generic.
- Report arity mismatches for undersaturated calls with unknown
parameters

# New Non-Strict
- Extends the new non-strict mode to report unknown symbols in types 

# Old Solver
- Fix a crash caused by excessive stack usage during typechecking

# Misc
- Improvements to Concrete Syntax Tree location tracking for string
table props.
