feat(ppa): add PPA driver support for ESP32P4

Browse Source 
Add burst_length option to client
Change uint32_t to color_pixel_rgb888_data_t
Descriptor always malloc with MALLOC_CAP_INTERNAL | MALLOC_CAP_8BIT
Add dscr-port mode block size configuration as a separate API in 2D-DMA driver
Do writeback only on an extended window, instead of entire picture
