GAPI: Add OAK backend * Initial tests and cmake integration * Add a public header and change tests * Stub initial empty template for the OAK backend * WIP * WIP * WIP * WIP * Runtime dai hang debug * Refactoring * Fix hang and debug frame data * Fix frame size * Fix data size issue * Move test code to sample * tmp refactoring * WIP: Code refactoring except for the backend * WIP: Add non-camera sample * Fix samples * Backend refactoring wip * Backend rework wip * Backend rework wip * Remove mat encoder * Fix namespace * Minor backend fixes * Fix hetero sample and refactor backend * Change linking logic in the backend * Fix oak sample * Fix working with ins/outs in OAK island * Trying to fix nv12 problem * Make both samples work * Small refactoring * Remove meta args * WIP refactoring kernel API * Change in/out args API for kernels * Fix build * Fix cmake warning * Partially address review comments * Partially address review comments * Address remaining comments * Add memory ownership * Change pointer-to-pointer to reference-to-pointer * Remove unnecessary reference wrappers * Apply review comments * Check that graph contains only one OAK island * Minor refactoring * Address review comments
