bootstat: Update boot reason property earlier

bootstat updates boot reason upon boot_complete, however users of the
updated properties e.g. getLastShutdownReason from PowerManager could
be called before boot_complete. This introduces a inconsistency and
racing for those APIs.

In this CL, we change boot reason to be updated at the same time when
zygote starts where persist properties have been loaded already. Also
the initialization of bootloader's boot reason is pulled into post-fs
where all kernel command line arguments have been parsed in init already.

Bug: 122696730
Bug: 119509425
Test: trigger thermal shutdown and see warnings
Test: verify boot reason properties updated correctly post boot
