Add int32 and int64 ArgMax op support

This patch adds int32 and int64 ArgMax op support.

Current ARMNN already has ArgMax op but not used, and
it doesn't support int64 output type.

So this patch adds a new type, Signed64, and also adds
ArgMinMax computation function for int64 type support.

In default, output tensor type of ArgMax op is int64 in case of
tensorflow lite model so this patch makes a proper function - ArgMax op
for int64 or int32 - to be called according to parsed output_type value.

With this patch, ARMNN supports both types - int64 and int32 - for
ArgMinMax op.

Changelog v1:
- Check if output data type of ArgMinMax op is valid or not.
- Use template function to support int32 and int64 types of ArgMinMax function.
- Keep using Signed32 as default data type of m_Output_Type.
