`kthvalue()` cannot be used with `complex` or `bool` type of a 1D or more D tensor but `kthvalue()` can be used with `complex` or `bool` type of a 0D tensor

🐛 Describe the bug

It seems like kthvalue() cannot be used with complex type of a 1D or more D tensor according to the errors as shown below:

complex type of a 1D tensor:

import torch

my_tensor = torch.tensor([0.+0.j, 1.+0.j, 2.+0.j], device='cpu')

torch.kthvalue(input=my_tensor, k=2) # RuntimeError: "kthvalue_cpu" not implemented for 'ComplexFloat'

my_tensor = torch.tensor([0.+0.j, 1.+0.j, 2.+0.j], device='cuda:0')

torch.kthvalue(input=my_tensor, k=2) # RuntimeError: "kthvalue_cuda" not implemented for 'ComplexFloat'

bool type of a 1D tensor:

import torch

my_tensor = torch.tensor([True, False, True], device='cpu')

torch.kthvalue(input=my_tensor, k=2) # RuntimeError: "kthvalue_cpu" not implemented for 'Bool'

my_tensor = torch.tensor([True, False, True], device='cuda:0')

torch.kthvalue(input=my_tensor, k=2) # RuntimeError: "kthvalue_cuda" not implemented for 'Bool'

complex type of a 2D tensor:

import torch

my_tensor = torch.tensor([[0.+0.j, 1.+0.j], [2.+0.j, 3.+0.j]], device='cpu')

torch.kthvalue(input=my_tensor, k=2) # RuntimeError: "kthvalue_cpu" not implemented for 'ComplexFloat'

my_tensor = torch.tensor([[0.+0.j, 1.+0.j], [2.+0.j, 3.+0.j]], device='cuda:0')

torch.kthvalue(input=my_tensor, k=2) # RuntimeError: "kthvalue_cuda" not implemented for 'ComplexFloat'

bool type of a 2D tensor:

import torch

my_tensor = torch.tensor([[True, False], [False, True]], device='cpu')

torch.kthvalue(input=my_tensor, k=2)  # RuntimeError: "kthvalue_cpu" not implemented for 'Bool'

my_tensor = torch.tensor([[True, False], [False, True]], device='cuda:0')

torch.kthvalue(input=my_tensor, k=2) # RuntimeError: "kthvalue_cuda" not implemented for 'Bool'

But kthvalue() can be used with complex or bool type of a 0D tensor as shown below:

complex type of a 0D tensor:

import torch

my_tensor = torch.tensor(0.+0.j, device='cpu')

torch.kthvalue(input=my_tensor, k=1)
# torch.return_types.kthvalue(
# values=tensor(0.+0.j),
# indices=tensor(0))

my_tensor = torch.tensor(0.+0.j, device='cuda:0')

torch.kthvalue(input=my_tensor, k=1)
# torch.return_types.kthvalue(
# values=tensor(0.+0.j, device='cuda:0'),
# indices=tensor(0, device='cuda:0'))

bool type of a 0D tensor:

import torch

my_tensor = torch.tensor(True, device='cpu')

torch.kthvalue(input=my_tensor, k=1)
# torch.return_types.kthvalue(
# values=tensor(True),
# indices=tensor(0))

my_tensor = torch.tensor(True, device='cuda:0')

torch.kthvalue(input=my_tensor, k=1)
# torch.return_types.kthvalue(
# values=tensor(True),
# indices=tensor(0))

Do these dtypes have a semantic ordering?
