add prebuilt kernels and modules for xz2, xz2c, xz2p and xz3 devices

built from sony tama OSS package (not SODP), with following patches:

- added support for reboot into EDL mode
- adapted tama dts to be compatible with both stock fw and LOS builds
- disabled skip_initramfs kernel param to allow 'fastboot boot'
- disabled avb on vendor in device tree fstab as done in LOS
- cherry picked sdm845 tama common fix invalid thermal trips LOS patch

also add dtbo for each device prebuilt kernel

this is just for reference, built twrp can 'fastboot boot' if stock
dtbo is present (including stock based modifications done in Lineage
OS for tama devices - tested with LOS 22.1)

kernel modules are shared for all models
