Bug Union init - C backend + Cpython + Lpython tests

[ronnuriel]

Cpython runtime error:

Traceback (most recent call last):
    from common import cht_test_st

    class cht_test_st(Union):

    cpy_imm_16_st: cht_cpy_imm_16_st = cht_cpy_imm_16_st()
TypeError: cht_cpy_imm_16_st.__init__() missing 6 required positional arguments: 'test_case', 'num_iters', 'cycles_count', 'seu_insts_count', 'imm_val', and 'vdst_hndl'

My Unions:

from lpython import packed, dataclass, i8, u8, u16, i64, i32, u32, u64, u16, ccall, union, Union


@packed
@dataclass
class cht_cpy_imm_16_st:
    test_case: u16
    num_iters: i64
    cycles_count: u64
    seu_insts_count: u64
    imm_val:  u16
    vdst_hndl: u64

@ccall
@union
class cht_test_st(Union):
    test_indx: u32
    cpy_imm_16_st: cht_cpy_imm_16_st = cht_cpy_imm_16_st()

Please test again union_02.py using Cpython run

Cpython error when running union_02.py

Yes, cpython tests are not enabled for union_02.py

Ah, we need to fix this. It looks like LPython works for the file, but not CPython, which is a bug that we need to fix. Thanks for the report @ronnuriel!
