bindings/wasm: Fix VFS.sync() function signature
...
We don't expect any return value from the underlying `fsync()` so fix
the function signature accordingly.
Fixes the following obscure error:
```
TypeError: Cannot convert undefined to a BigInt

Merge 'btree: cursor with lineal stack structure' from Pere Diaz Bou
...
Removed MemPage from the code in favor of an array to encode the stack
of the cursor. This is both simpler and better in terms of memory
access.
O_DIRECT was removed from WAL file as it introduces alignment
constraints that are too hard to follow in regular appends. Maybe in the
future?
Closes #378

wasm: VFS interface to use Node filesystem API

This adds a basic VFS interface to use Node filesystem API from Rust
