On builds where A/B support is enabled the system image acts as the
rootfs. In this case we can no longer create the non-hlos image mount
points at run time as we used to. We now create them as part of the
build itself.

This can be checked by looking for a rild service in system.
If it's missing, then a vendor ril service is being used, in
our case, it is qcrild.

Partitions that use vbmeta_system can be found by looking at
avb flag in fstab from boot ramdisk.
--flags 2 makes the verification function of avb always return a
positive result.
--set_hashtree_disabled_flag builds the vbmeta images with the
HASHTREE_DISABLED bit set and as a result they don't need to manually
disable dm-verity via e.g. 'adb disable-verity'.
The rest of the configuration is taken from

Partition sizes can be found by query-ing sysfs.
For example, for super partition.
> ls -la /dev/block/by-name/super
lrwxrwxrwx 1 root root 16 1970-03-23 06:51 super -> /dev/block/sda17
> cat /proc/partitions | grep sda17
259 1 8388608 sda17
The size needs to be multiplied by the block size used by
/proc/partitions, which is 1024 bytes.
Logical partitions found inside the physical super partition
can be found by looking for entries with the logical flag in the
fstab inside boot ramdisk.
Add device compatibility matrix to common project and
targets can point the build variable DEVICE_MATRIX_FILE to
this file to build device compatibility matrix.

* Straight from CAF (as per LA.UM.6.3.r4-04300-sdm845.0),
with BTM_DEF_LOCAL_NAME unset so that ro.product.model
is used instead.

USE_CUSTOM_AUDIO_POLICY guards out the AOSP audio policy,
while guarding in the CAF audio policy.

for audio policy.
