fix(ext/node): Fix fs.access/fs.promises.access with X_OK mode parameter on Windows (#27407)

- Fixes an issue on Windows where the `fs.constants.X_OK` flag caused
`fs.access` and `fs.promises.access` to incorrectly throw a "permission
denied" error
- Introduced formatting changes due to the formatting tool
- Fixed the issue by always removing the `X_OK` bit from the mode
variable m (not sure if it's necessary to check for the presence of it
in the `mode` param first?)
- Updated unit tests to handle the mentioned constant
- `X_OK` bit is ignored in the Node implementation and should behave
like `F_OK`
