Add some OTA related entries to misc_info.txt

Corresponding make code: https://cs.android.com/android/_/android/platform/build/+/8445b1703a24d34a2c6fc789f47cf81ceda3aaea:core/Makefile;l=5957-5965;drc=519f75666431ee2926e0ec8991c682b28a4c9521;bpv=1;bpt=0

This adds a subset of the args passed to mkbootimg cmd of the bootimg
deps. For cuttlefish, `header_version` seems to be the only argument
added to BOARD_*_MKBOOTIMG_ARGS.

Bug: 398036609
