This patch moves language- and target-specific functions out of `SemaDeclAttr.cpp`. As a consequence, `SemaAVR`, `SemaM68k`, `SemaMSP430`, `SemaOpenCL`, `SemaSwift` were created (but they are not the only languages and targets affected). Notable things are that `Sema.h` actually grew a bit, because of templated helpers that rely on `Sema` that I had to make available from outside of `SemaDeclAttr.cpp`. I also had to left CUDA-related in `SemaDeclAttr.cpp`, because it looks like HIP is building up on top of CUDA attributes. This is a follow-up to #93179 and continuation of efforts to split `Sema` up. Additional context can be found in #84184 and #92682.
