feat(fsx): support HDD storage type for a Lustre file systems (#30207)

### Issue # (if applicable)

Closes #30206.

### Reason for this change

AWS FSx for Luster file systems supports HDD storage type and LusterFileSystem construct cannot configure it.

### Description of changes

- Add `storageType` for `fsx.FileStstemProps`
  - For future expansion, `storageType` is added not to `LusterFileSystemProps` but to `FileSystemProps` because HDD storage is also supported by Windows file systems.
- Update the validation of the props below to address the HDD storage type.
  - `LusterConfiguration.perUnitStorageThroughput`
  - `FileSystemProps.storageCapacityGiB`

### Description of how you validated changes

Added both unit and integ tests.
