Enable SSH connectivity for Developer SKU

[anvrao1]

---

This PR enables SSH connectivity for the Developer SKU by replacing the direct SKU and tunneling check with a unified helper function.

Introduce _is_nativeclient_enabled to allow Developer SKU by default and preserve existing checks for Standard/Premium.
Replace the original SKU-plus-tunneling conditional with a call to the new helper.
Retain the error-raising logic, now backed by the helper function.

• The exception message still references only Standard or Premium SKUs, but Developer SKU is now supported; consider updating it to mention Developer support explicitly.

raise ClientRequestError('Bastion Host SKU must be Standard or Premium and Native Client must be enabled.')

src/bastion/azext_bastion/custom.py:390

• Add unit tests for _is_nativeclient_enabled to cover the Developer SKU path and verify behavior across all supported SKUs.

[nitpick] The nested ternary conditional within _is_nativeclient_enabled is hard to follow; refactor it into a clear if/elif/else block for better readability.
