fix(driver): allocate driver objects containing atomic variables from internal SRAM

Browse Source 
Objects with atomic members must not be allocated to PSRAM, otherwise
the ordering guarantee of atomic accesses is weakened due to a hardware
behavior on ESP32 chips. Explicitly request MALLOC_CAP_INTERNAL |
MALLOC_CAP_8BIT for:

- i2c master bus object (atomic status/trans_idx)
- i3c master bus object (atomic fsm)
- ISP processor and AE/AF/AWB/HIST controllers (atomic fsm)
- JPEG decoder/encoder dma2d transaction descriptors (atomic started)
- PPA transaction storage embedding dma2d_trans_t
- dma2d m2m test transaction embedding dma2d_trans_t
