nine: Gallium Nine'i Mesa 26.x'e forward-port et

Nine Mesa 25.2'de silindi. Bu commit onu 26.2 agacina geri getiriyor:
src/gallium/frontends/nine, src/gallium/targets/d3dadapter9, D3D9 ve
d3dadapter basliklari, meson entegrasyonu ve driconf secenekleri.

Silinmesinden sonra gallium'da degisen ve uyum gerektiren yerler:
  - mesa_shader_stage, enum pipe_shader_type'in yerini aldi
  - pipe_surface de-pointerize edildi, create_surface kalkti
  - u_upload_data/alloc artik referans vermiyor; _ref varyantlarina gecildi
  - threaded_context kullanici sabit tamponlarini yuklemiyor (MR 36715),
    tc_set_constant_buffer'da assert(!cb->user_buffer) var. SWVP ve
    fixed-function yollari icin nine_upload_constant_buffer() eklendi.
  - driParseConfigFiles struct API'sine gecti

Ayrica D3D9'un ugradigi ama GL frontend'inin hic gecmedigi uc yolda
surucu hatasi cikti; ucu de burada:

  crocus_query.c   PIPE_QUERY_GPU_FINISHED ele alinmiyordu
  crocus_clear.c   clear_render_target gelen pipe_surface'i crocus_surface'e
                   cast edip ->view okuyordu; Nine kendi surface'ini
                   uretiyor, format crocus_format_for_usage ile yeniden
                   turetiliyor
  tgsi_to_nir.c    TXD'de ddx/ddy bilesen sayisi kirpilmiyordu

Gercek donanimda dogrulandi (8086:0166, crocus, wine 11.0 +
wine-nine-standalone): Max Payne 2, The Witcher EE, Fallout New Vegas,
Warband, L4D1, PAYDAY: The Heist calisiyor.
