sokol: upgrade to latest version, add program icon support (#11559)

* updated sokol_gfx.h to the last version: 16d7b2e

* merged sokol_app and update enums.v

* added missing icons structs

* try to fixing Mac keyboard problems

* added v patch marker to sokol_app.h

* upgrade for sokol_gl.h, sokol_fontstash.h

* manage sgl_load_default_pipeline

* added load_default_pipeline() for sokol coherence

* vfmt sapp_structs.c.v
