fix: LVGL rendering for 16bpp framebuffers (HyperV compatibility)

The LVGL flush callback assumed 32bpp (4-byte stride, direct pixel
copy), causing corrupted output on hypervisors that fall back to
16bpp modes (e.g. HyperV at 1600x1200x16).

- lvgl.pas: Make lvgl_flush_cb BPP-aware; add ARGB8888->RGB565
  conversion path for 16bpp, keep direct copy for 32bpp. Replace
  static lv_buf1 array (hardcoded 1600px wide) with kalloc'd buffer
  sized to actual screen width.
- doublebuffer.pas: Fix allocateBackBuffer size from (W*H*BPP) to
  (W*H*BPP) div 8 to get correct byte count.
- vesa.pas: Account for BPP in allocateVESAFrameBuffer page range
  calculation to avoid under-mapping at higher BPP/resolutions.
- Removed the initialization of console in kernel.pas as this will
  cause issues on some systems that don't expect to need to allocate the
  textmode buffer.
