Switch 2: window image sizes, queue semaphores, built-in fonts, memory budget

- gsv 1510 CalculateRequirements: block-linear size/alignment for window images.
- nvhost-gpu: Switch 2 channel event 7 is a real (unsignalled) event.
- Puller mirrors NVN2 queue semaphore releases into the page the CPU and GPU
  wait on (the first two-page nx2:gpu region); EDEN_NX2_METHOD_TRACE logs methods.
- pl:u 2000/2010 GetBuiltInFontSharedMemory/GetBuiltInFontData serve plain TTF
  copies of the shared fonts.
- Switch 2 processes count the alias region in their max memory, so the game's
  nninitStartup heap (total - 6.3 GiB) has room for its sound heap.
- gdbrsp.py: interrupt, threads, selthread, hits, continue_async, sleep.
