VSCode IDE enhancement and readme update (#3172)

- Temporarily disable the deque test for the VS Code extension, as the
  Rust formatter seems to malfunction after a recent VS Code update.
- Add configuration for iwasm host managed heap size, allowing users
  to flexibly `malloc` memory. This also fixes the current bug that when
  default size is 0, it can't run and debug.
- Apply coding style formatting for WAMR IDE source code and add a
  format check for it in CI.
- Update document and some screenshots.
