Numba ifelse does not copy inputs when not inplace

[ricardoV94]

Description

This breaks the semantics of ifelse and can even cause errors when trying to mutate a global array which is non-mutable by default in numba:

import pytensor
import pytensor.tensor as pt
from pytensor.compile.mode import Mode

x = pt.vector("x")
out = pytensor.ifelse(x.sum() > 0, x, x)
fn = pytensor.function([x], out, mode=Mode("numba", optimizer=None))
fn.dprint(print_memory_map=True)  # Not a view
# if{} [id A] 2
#  ├─ Gt [id B] 1
#  │  ├─ Sum{axes=None} [id C] 0
#  │  │  └─ x [id D]
#  │  └─ 0 [id E]
#  ├─ x [id D]
#  └─ x [id D]
x_test = np.zeros((5,))
assert fn(x_test) is not x_test  # Fails
