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.

Build/test wasm32-wasip2 in CI ( #649 )
...
This is a follow-up from mlua-rs/lua-src-rs#13 which verifies/tests that
mlua/lua all work when compiled for a WASI target. While this doesn't
have formal documentation yet it also codifies in CI configuration how
to build for WASI and get tests passing (notably C compiler
configuration and some misc Rust flags).
This moves some `dev-dependencies` that don't compile for
`wasm32-wasip2` to a different section of the manifest. This
additionally annotates panicking tests with `#[cfg(not(panic =
"abort"))]` to skip those tests on WASI.
This does not test either the `send` or `async` feature at this time.
Testing `send` requires threads which WASI does not yet support, and
testing `async` requires more support in Tokio which is not currently
there yet.

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.
