Port new BlobType fields file_extension and enable_legacy_filename to flytekit.
FlyteFile inputs can be annotated with the FileDownloadConfig annotation to
configure the file extension to use during the copilot download phase.
e.g.
```python
def t1(file: Annotated[FlyteFile, FileDownloadConfig(file_extension="csv")]):
... # copilot downloads the file to e.g. /inputs/file.csv
versus...
def t1(file: FlyteFile["csv"]):
... # copilot downloads the file to e.g. /inputs/file
```
