Add lua_cleartable (#678)
To my understanding lua_cleartable does not need GC barriers because
it's only removing elements and not modifying the stack. But I'm not a
GC expert so please correct if I'm wrong.

resolves #672

Add lua_rawsetfield (#671)
Luau currently has the following functions in the C API for dealing with
tables without invoking metamethods:

lua_rawgetfield
lua_rawget
lua_rawgeti
lua_rawset
lua_rawseti

This change adds the missing function lua_rawsetfield for consistency
and because it's more efficient to use it in place of plain lua_rawset
which requires pushing the key and value separately.

Feat: Added retry functionality to benchmarks (#667)
Resolves #668 

## The problem
Benchmarks jobs run concurrently for the different operating systems.
This means that when it comes time to push the benchmark results to [the
assigned benchmark results
repo](https://github.com/luau-lang/benchmark-data), there can be two
different jobs trying to push changes at the same time. In such a case,
one of the pushes will fail and we end up missing some benchmark results
data from the workflow run.

## The solution
Whenever a push fails, we need to retry the steps leading up to the push
(checking out the benchmark results repo, storing benchmark results,
pushing the results to [a specific
repo](https://github.com/luau-lang/benchmark-data)).

### Note
There are 3 push attempts before submitting to failure.

## TL;DR
This PR retries pushing benchmark results when they fail to get pushed
(often due to pushing from multiple jobs concurrently)

- Remove type definitions of
`utf8.nfcnormalize`/`nfdnormalize`/`graphemes` that aren't supported by
standalone Luau library
- Add `lua_costatus` to retrieve extended thread status (similar to
`coroutine.status`)
- Improve GC sweeping performance (2-10% improvement on allocation-heavy

RFC: Prohibit use of interpolated strings in function calls without parentheses (#648)
We've had this restriction in the original RFC, but decided to remove it afterwards. This change puts the restriction back - we need to work through some implications of future support for string-based DSLs together with interpolated strings which may or may not change the behavior here, for example to allow something like

```
local fragment = xml `
  <img src="{self.url}" />
`
```

- Fix DeprecatedGlobal warning text in cases when the global is deprecated without a suggested alternative
- Fix an off-by-one error in type error text for incorrect use of string.format
- Reduce stack consumption further during parsing, hopefully eliminating stack overflows during parsing/compilation for good
- Mark interpolated string support as experimental (requires --fflags=LuauInterpolatedStringBaseSupport to enable)
- Simplify garbage collection treatment of upvalues, reducing cache misses during sweeping stage and reducing the cost of upvalue assignment (SETUPVAL); supersedes #643
- Simplify garbage collection treatment of sleeping threads
- Simplify sweeping of alive threads, reducing cache misses during sweeping stage
- Simplify management of string buffers, removing redundant linked list operations

RFC: Explicitly support escape sequence in string interpolation literals (#642)
This was implicitly assumed to be supported, but we should really just say so explicitly. If we didn't, there'd be two ways to interpret it: string interpolations are raw strings and escape sequences don't exist for the most part (false), or string interpolations are like strings and escape sequences do exist (true).

Also talks about the ambiguity with `\u{` and that it is defined to take priority and does not terminate the interpolation chunk and starts a new expression, instead it must be a well-formed escape sequence `\u{...}`. It is very unlikely there'd be another escape sequence that also has this same ambiguity problem, so we don't need to worry about this.

Pass environment scope to autocomplete typechecker (#610)
Fixes a bug where the environment scope is not passed to the autocomplete typechecker, so environment-related types are not provided.

This caused an issue where `getModuleEnvironment` returns `typeChecker.globalScope` when there is no environment. We pass this through to `typeCheckerForAutocomplete.check()` then environmentscope is no longer nullopt and it will use `typeChecker.globalScope` instead of falling back to `typeCheckerForAutocomplete.globalScope`.

This is solved by passing `forAutocomplete` to `getModuleEnvironment` so it falls back to the autocomplete global scope if none found.

Prevent overflow in lua_newuserdatadtor (#639)
In case a large userdata size is passed to lua_newuserdatadtor it might overflow the size resulting in luaU_newudata actually allocating the object without a memory error. This will then result in overwriting part of the metatable pointer of the userdata.
This PR fixes this issue by checking for the overflow and in such cases pass a size value which will cause a memory error in luaU_newudata.

Add autocomplete context to result (#611)

Not sure if these context definitions are distinct enough, but they work for my use cases.
