When compositing transforms lots of temporary of arrays will be created
and passed to next primitive, and by making ops accepting args by value
we can avoid lots of copies of temporary arrays.
Without the && args would be copied and perfect forwarding won't work.
Also add template utils to make sure the function only forwards array
and not vector<array>.
* add numeric type hierarchy and issubdtype as well as a set_dtype method to nn.Module with predicate
numeric type hierarchy and issubtype is compatible to the [numpy hierarchy](220f0ab2c5/numpy/_core/numerictypes.py (L42)).
Closes#285.

1. Move shapes into outputs instead of copying them.
2. Pass primitive by const ref as it is always copied into outputs, which
removes a copy when calling make_array.

To avoid eval calling itself recursively, the vector version of eval is
changed to take by value instead, which will save a copy of array when a
rvalue is passed.
* Update mlx_set_item to handle regular slices without expanding
* Refactor ellipsis handling
* Route mlx_set_item to slice_update where possible
* Update mlx_scatter_args_slice
* Don't route to gather if no array indices
* Enable copy to work with int64 strides
* Fix uniform buffer indices or copy kernel arguments
* Update utils.h
* Remove manual unrolling of elem to loc loop
* GPU copy updated to handle negative strides
* Add slice update primitive
Since the shape and inputs are always saved as copy in ArrayDesc, we can
unify array's constructors to just take the arguments by value.
There are 2 cases:
1. When shape is a lvalue, it will be copied into array's constructor and
then moved into ArrayDesc's member. So only 1 copy happens.
2. When shape is a rvalue, it will be moved into array's constructor and
then moved into ArrayDesc's member. So no copy happens.
So having 1 constructor that takes by value is equivalent to having 2
constructors that const reference and rvalue separately.

1. Anonymous namespace means internal linkage, static keyword is not needed.
2. The default constructor of std::shared_ptr initializes the pointer to
nullptr, you don't need to explicitly set it.
