This adds a sanity check in addition to the version number in case misc
contains random bits.

Move merge_status from bootloader_control_ab, which is in vendor space,
to a new generic AOSP struct in system space. This will allow more
devices to share the same HAL implementation.
This patch also changes libboot_control to compensate for merge_status
moving out of vendor space. The reference HAL library now also provides
separate helper functions for managing the merge status, so devices
using a custom boot control HAL can still take advantage of the new misc
implementation.

`misc_device_` is a std::string, so it allocates and manages its own
memory. Hence, the strdup here is immediately leaked.

If the HAL is run on a non-A/B device, it does not fail gracefully; it
will segfault because the current_slot is -1 and methods do not protect
against this. Instead, have Init() fail if we can't determine the
current slot.

This extracts the implementation of boot_control into a new library,
libboot_control. The bootctrl.default module now wraps this library.
This refactoring will allow us to re-use the same implementation in
HIDL.

The added bootctrl.bcb module implement the legacy interface for the
bootctrl HAL based on the Boot Control Block (BCB) and the headers
already specified in the booloader_message library.
This serves as a reference implementation of the boot_control HAL.
Bug: 32707546
Test: Tested internally that a device can use this HAL to flip slots and
recovery from a /misc wipe.
