Add avb info of bootimages in misc_info.txt

Make built $ANDROID_PRODUCT_OUT/misc_info.txt contains the avb
information of the installed boot images. This info overlaps with the
contents of the buildPropFile of the `bootImg` modules, but
- Only some of the entries are written to misc_info.txt
- misc_info.txt contains the "partition qualified" key. e.g.
  avb_init_boot_algorithm and not avb_algorithm

This CL adds a secondary `propFileForMiscInfo` to the build actions
of bootimg. This file will be propagated to android_device via a
provider and cat'd to the misc_info.txt created by android_device

(There are still a lot of diffs between Make and Soong misc_info.txt)

Bug: 398036609
Test: Built Soong's misc_info.txt
