Issues when enabling Mandelbrot

[mingjie-intel]

This is used to track issues during enabling Mandelbrot test case.

• [ ] #1013
• [ ] CFD pass to support function calls inside a dpjit function.
• [ ] Calling dpjit within dpjit #989

Reproducers are attached.

Reproducer for dpnp.asarray:

import dpnp
from numba_dpex import dpjit

@dpjit
def foo(a):
    b=dpnp.asarray([0.1,0.2,0.3])
    a=b
    
a=dpnp.empty(3) 
foo(a)
print(a)
