pwrctl: Add latch output to power control

On the Zaius machine, the BMC signals that power up the CPU are gated by
a latch to protect against GPIO blips during BMC reset/power loss.

This adds an optional power GPIO configuration that controls the latch's
enable pin. Its behavior is to assert high when the op-pwrctl runs,
allowing power_up lines to propagate past their latches.

system_manager, libobmc-intf: Add power GPIO configuration interface

This adds a dbus call (in org.openbmc.managers.System) and C binding (in
libopenbmc-intf) to read a POWER_CONFIG from the Python system
configuration that abstracts GPIO functionality (power good, reset, etc)
from their net names in GPIO_CONFIG.

This should eventually replace machine-specific patches to op-pwrctl
that define their own power and reset lines.

Reorganize directory structure

Moving to directory per-application layout. This facilitates
building single applications which is useful in the Yocto build
environment since different applications satisfy different OpenBMC
build requirements.

A number of issues are also addressed:
- All applications were pulling in libsystemd and the gdbus libs
irrespective of whether or not they were needed.
- gpio.o duplicated in every application - moved to libopenbmc_intf
- Added install target
