Add Support for FPGA Bitstream Preset-registers (#1050)
Introduce Preset Register Specialized Emission
- Introduce EmissionOption trait
- Introduce PresetAnnotation & PresetRegAnnotation
- Enable the collection of Annotations in the Emitter
- Introduce collection mechanism for EmissionOptions in the Emitter
