Reduce number of allocations when calling async function
...
Instead of creating a uniq poller with upvalue on each async call, return future directly
and pass it to the poller
This also gives about 3-5% perf improvements

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.

Use to_bits comparison to check if a float value can be represented as an integer losslessly.

This allows to simplify the code while still maintaining "negative zeros" edge case.
Thanks @JasonHise for the suggestion.

Better handling negative zeros to match Lua 5.3+ behavior
...
In Lua 5.3+ the function `lua_isinteger` returns "false" for -0.0 numbers.
In earlier Lua versions we should follow the same behavior to avoid losing the sign when converting to Integer.

Don't panic when fourth library searcher does not exists.
...
When disabling C modules, we remove the last two searchers (C & C all-in-one).
In Pluto the C searches may not exist by design, in this case check that 4th searcher is present before removing it.

Terminate underlying Rust future when AsyncThread is dropped.

Before this change, Lua GC was responsible to collect and destroy the future if
`AsyncThread` dropped in yielded state.
Now we will propagate "drop" event immediately so Lua GC need to only free the memory.

Support new Luau require system

By default mlua implements behaviour same as `ReplRequirer` in the original Luau.
Unfortunately binary Luau modules are no longer supported by the new system.

We need this because they have different requirements:
- Thread creation callback can return Error or panic
- Thread collection callback runs during Luau GC cycle and cannot make any Lua calls or trigger panics.

Don't store and use wrong main Lua state in module mode (Lua 5.1/JIT only).
...
When mlua module is loaded from a non-main coroutine we store a reference to it to use later.
If the coroutine is destroyed by GC we can pass a wrong pointer to Lua that will trigger a segfault.
Instead, set main_state as Option and use current (active) state if needed.
