Remove unmaintained wee_alloc dependency (#2245)

* Remove unmaintained wee_alloc dependency

Switch flow-web crate from wee_alloc to Rust's default allocator for
wasm32 targets. The wee_alloc crate is unmaintained and the default
allocator now provides better performance and maintenance.

Changes:
- Remove wee_alloc dependency from workspace Cargo.toml
- Remove wee_alloc feature from flow-web/Cargo.toml
- Remove wee_alloc global allocator setup from flow-web/src/lib.rs
