Refactor boot_control into a separate library.
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.
Bug: 138861550
Test: mm bootctrl.default
