Loss of functionality in .54 - change in slicing behavior on user defined types

possible dupe of : https://github.com/numba/numba/issues/7355 The following code worked prior to 0.54, but no longer will run:

import numpy as np
import numba as nb

ALT_TYPE = [('Z', np.float64, 3)]
np_alt = np.dtype(ALT_TYPE, align=True)
nb_alt = nb.from_dtype(np_alt)
print(np_alt)
print(nb_alt)


@nb.njit(nb.void(nb_alt[:]))
def new_kern(z):
    z[0]['Z'][:] = 7


dta = np.zeros((1,), dtype=nb_alt)
new_kern(dta)
print(dta)

Yields:

No implementation of function Function(<built-in function setitem>) found for signature:
 
 >>> setitem(nestedarray(float64, (3,)), slice<a:b>, Literal[int](7))
 
There are 16 candidate implementations:
  - Of which 14 did not match due to:
  Overload of function 'setitem': File: <numerous>: Line N/A.
    With argument(s): '(nestedarray(float64, (3,)), slice<a:b>, int64)':
   No match.
  - Of which 2 did not match due to:
  Overload in function 'SetItemBuffer.generic': File: numba\core\typing\arraydecl.py: Line 171.
    With argument(s): '(nestedarray(float64, (3,)), slice<a:b>, int64)':
   Rejected as the implementation raised a specific error:
     TypeError: __init__() got an unexpected keyword argument 'ndim'

Expected behavior: [([7,7,7],)]

The bug affects CUDA as well but this is probably incidental.

Closing now as #7428 was merged!

I can confirm that #7428 will fix this too.

can confirm that fixes it

Great, thank you!
