drm/amd/display: Introduce DML2

DC is transitioning from DML to DML2, and this commit introduces all the
required changes for some of the already available ASICs and adds the
required code infra to support new ASICs under DML2. DML2 is also a
generated code that provides better mode verification and programming
models for software/hardware, and it enables a better way to create
validation tools. This version is more like a middle step to the
complete transition to the DML2 version.

Changes since V1:
- Alex: Fix typos

Changes since V2:
- Update DC includes

Changes since V3:
- Fix 32 bit compilation issues on x86

Changes since V4:
- Avoid compilation of DML2 on some not supported 32-bit architecture
- Update commit message
