CUDA/C++ backend improvements (#1198)

* WIP with vector float test.

* vector-float test working.

* Fixed remaing tests broken with init changes.

* Improve 64bit-type-support.md

* Disable tests broken on CI system for Dx.

* WIP: Make type available for comparison.

* Moved type conversion into TypeTextUtil.

* Add text/type conversions from DownstreamCompiler to TypeTextUtil.

* Allow compaison taking into account type.

* Removed quantize in vector-float.slang test.
