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
...
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.

(Luau Require) Resolve Lua file path relative to the current directory
...
and unrelated to Rust source file location.
When a Lua file is required inside a Rust file (in a chunk), we should resolve the Lua file relative to the current directory,
instead of relative to the Rust chunk path.
The Rust file location is an internal information that does not exist when the compiled binary runs.
