pw_boot: Create pw_boot facade

Move the header file out of pw_boot_armv7m to serve as a public API
for the facade, making pw_boot_armv7m the implementation.

This allows targets to provide an alternate implementation of
pw_boot_Entry.

This is not possible today due to the implementation dependency in
pw_malloc_freelist which, with this change, is moved to the facade
instead.

Update includes in existing targets to use the new path and dependency,
they were already setting pw_boot_BACKEND.
