BUG: fix asanyarray fallback

[samir-nasibli]

Description

• removed dpnp error raise, fallback when order is not c contiguous
  DPNP error: in function asanyarray() paramenter 'order' expected C, but 'None' provided -> 'int' object has no attribute 'c_contiguous'
• disabled tests for ['int' object has no attribute 'c_contiguous']. See Reproduce dpctl usm_array flags below

Now there are another fail on test:

tests/third_party/cupy/creation_tests/test_from_data.py:369: in test_asanyarray_with_order
    assert b.flags.c_contiguous
E   AssertionError: Only cupy raises error
E

E       assert b.flags.c_contiguous
E   'int' object has no attribute 'c_contiguous'

This fail happens due dpctl usm_ndarray, that have a bug for flags.

Reproduce dpctl usm_array flags

>>> a = dpnp.asanyarray([12,34], order='C')
>>> a = dpnp.asanyarray([12,34], order='K')
>>> a
<dpctl.tensor._usmarray.usm_ndarray object at 0x7fdec18e4130>
>>> a.flags
1
>>> import numpy
>>> b = numpy.asanyarray([12,34], order='K')
>>> b.flags
  C_CONTIGUOUS : True
  F_CONTIGUOUS : True
  OWNDATA : True
  WRITEABLE : True
  ALIGNED : True
  WRITEBACKIFCOPY : False
  UPDATEIFCOPY : False

'int' object has no attribute 'c_contiguous'

@Alexander-Makaryev I have disabled tests that fail due dpctl bug (see. Reproduce dpctl usm_array flags on description). If it is necessary I will create issue for this on dpctl repo.

[Alexander-Makaryev]

@oleksandr-pavlyk Could you please look at it? Is Samir right?

[oleksandr-pavlyk]

usm_ndarray.flags indeed gives an integer, encoded using bits. Bit 0 is set if array is C-contiguous, bit 1 if F-contiguous and bit 2 if writeable.

[samir-nasibli]

@Alexander-Makaryev @oleksandr-pavlyk usm_ndarray interface is not compatible with these third-party/cupy test cases. numpy.ndarray for flags method returns numpy.flagsobj, while usm_ndarray returns int val for flags method. third-party/cupy test cases require flagsobj object. We shouldn't change third-party tests, we can only disable tests, what has already been done in this PR.

@samir-nasibli Could you please remove the skipping of tests from this PR?
