Add Luau.Ast.CLI target (#345)
Adds a `luau-ast` CLI that dumps Luau source to JSON. @asajeffrey and I are planning to use this functionality to construct an Agda model of the Luau type system/operational semantics, to allow formally proving properties of Luau's type systems.

Sync to upstream/release/512 (#330)
- Improve refinement support for unions, in particular it's now possible to implement tagged unions as a union of tables where individual branches use a string literal type for one of the fields.
- Fix `string.split` type information
- Optimize `select(_, ...)` to run in constant time (~2.7x faster on VariadicSelect benchmark)
- Improve debug line information for multi-line assignments
- Improve compilation of table literals when table keys are constant expressions/variables
- Use forward GC barrier for `setmetatable` which slightly accelerates GC progress

Sync to upstream/release/511 (#324)
- TableOperations lint now includes a warning for table.create(N, {}) (which is likely a mistake since the table is shared by all entries)
- Type checker now type checks #v when v is a union
- Parser now rejects sources that consists of a single unfinished long comment
- Work around significant MSVC 2022 performance regression, bringing it more or less in line with MSVC 2019
- Compiler now predicts array size for newly allocated tables when the table is filled in a short loop
- Small improvements in compilation throughput (~2% faster)
- Implement paged sweeper for GC which improves sweep throughput 2-3x and reduces memory consumption by 8 bytes per object (once it is stabilized we will see additional 8 bytes per object of savings)
- Improve Repl Tab completion
- Repl now supports -i (interactive mode to run code in context of a script's environment) and -On (to control optimization flags)

Add web workflow to build Repl with Emscripten (#222)
This also separates Emscripten build into a new target / source to make
it more decoupled.

Use -Werror in CI only (#201)
We keep getting compat reports for warnings in various compiler
versions. While we can keep merging PRs to resolve these warnings, it
would be nice if the users of other compilers or compiler versions weren't
blocked on us fixing this.

As such, this change disables Werror by default and only enables it when
requested, which happens in CI in test builds.

Feature: Web REPL using Emscripten (#138)
Currently doesn't include the new page into navigation since we aren't building the .js files anywhere.
