Add Lua::set_memory_category and Lua::heap_dump functions to profile Luau memory usage.
...
This functionality uses Luau private api to dump heap mempory in JSON format for inspection.
The new type `HeapDump` represents memory snapshot with some basic API to calculate stats.

Reduce number of allocations when calling async function

Instead of creating a uniq poller with upvalue on each async call, return future directly

Make Lua reference values cheap to clone
...
Instead of locking the VM and making a copy on auxiliary thread, track number of references using Rust ref counter.
This should also help reducing number of used references (they are limited to to 1M usually) on auxiliary thread.

Lower fastpath table creation limit to 1 << 26
...
When Lua is configured without memory restrictions, we use fastpath for table creation (unprotected mode).
In generally it's safe as long as we `abort()` on allocation failure.
However some Lua versions have additional restrictions on table size that we need to adhere in mlua too.
Probably Luau has the lowest limits.

Better handling negative zeros to match Lua 5.3+ behavior
