Adding complex value with 0 for real and imaginary part can be ignored.
NOTE: This type of canonicalization can be written in an easy and tidy format using `complex.number` after constant op supports custom attribute.

We can canonicalize consecutive complex.conj just by removing all conjugate operations.

It is more useful to use ComplexType as type of the attribute than to
use the element type as attribute type. This means when using this
attribute in complex::ConstantOp, we just need to check whether
the types match.

Add custom attribute for complex dialect. Although this commit does not have significant impact on the conversion framework, it will lead us to construct complex numbers in a readable and tidy manner.

Removed redundant ops from the standard dialect that were moved to the
`arith` or `math` dialects.
Renamed all instances of operations in the codebase and in tests.
