Added fixed-precision numbers using Int32 and Int64 base types. (#1162)
* Added new fixed precision computation types based on int and long types. * Added FixedIntConfig.ttinclude to control fixed precision type generation. * Added new generator template to ILGPU.Algorithms.csproj and adjusted ignore file. * Extended VectorTypes.tt to generate vector types for fixed precision int types. * Integrated fixed precision types with RandomRanges.tt.
