Enable min & max for Float16 & BFloat16 (#51244)
Summary:
Fixes https://github.com/pytorch/pytorch/issues/50790.
Added `min()` & `max()` support for `Float16` & `BFloat16`.
CUDA already supported these ops on `Float16`, so the other three combinations had to be enabled.
`OpInfo`s for `min` & `max` were also added, and their sample inputs were removed from `method_tests()`.
### MORE INFO
The (slightly) long-term goal is to add dispatch for `min()` & `max()` related operations on CPU & CUDA for `Float16` & `BFloat16`,
wherever they aren't present already:
1. `amin()`
2. `argmax()`
3. `amax()`
4. `argmin()`
5. `torch._aminmax()`
6. `torch.clamp()` on CPU. Was already supported on CUDA
7. `min()` (in this PR)
8. `max()` (in this PR)
9. `minimum()`
10. `maximum()`
I'll submit separate PRs for the other ops.
