soc/qualcomm/x1p42100: Add support for APDP image packing in CBFS

Browse source 
This patch adds build rules for packing the APDP image in CBFS.
It also updates the memory layout to include a dedicated region
for APDP metadata storage (4KB at 0x14890000).

TEST=Create an image.serial.bin and ensure it boots on X1P42100.
