Create a custom power button handler

IBM has specific requirements on how the power button must behave, which
are different than what the button handler currently does.

These requirements are:
If power is off:
- A button press will power on as long as the BMC is
in the ready state.

If power is on:
- A button press less than 4s won't do anything.
- At 4s, issue a host power off and start a 10s timer.
- If the button is released within that 10s and not pressed
again, continue with the host power off.
- If the button is released within that 10s and also
pressed again in that 10s, do a hard power (chassis)
off.
- If the button is pressed throughout that 10s
issue a hard power off.

Instead of trying to integrate this behavior into the main button
handler code using even more #ifdefs in various spots, this commit
creates the concept of custom power button handlers, and then implements
one. This makes it less likely it could subtly break when changes are
made to the default code.

A 'power-button-handler' meson option is used to select the handler,
where the default uses the current behavior. A
PowerButtonHandlerFactory then creates the appropriate instance of the
handler selected by that option. If a handler is found, then the
default matches/callbacks won't be done and the handler can deal with
them as it sees fit.

Handlers are derived from a PowerButtonHandler abstract base class that
has 2 pure virtual functions:
- void pressed();
- void released(uint64_t pressTimeMS);

It will register for the power button pressed/released signals and then
call these overridden functions appropriately.

This new handler is implemented in a HostThenChassisPowerOff class.

Support host selector using cpld definitions

Description:
- Support host selector using cpld definitions

Design:
- Because the current structure only supports config defined by GPIO
(Yosemite V2), but there are also have the system (Yosemite V3.5)
gets the host-selector's selection from CPLD.

- So this commit is to extend the current configuration to use CPLD
definitions. Also, support adding event io from the register file
which was exported from the CLD driver.

- For example with config json below:
{
"cpld_definitions": [
{
"name": "HOST_SELECTOR",
"i2c_address": 15,
"i2c_bus": 12,
"register_name": "uart-selection-debug-card",
"max_position": 4
}
]
}

Dependency:
- CLD driver is required (link: https://lore.kernel.org/lkml/20230117094425.19004-1-Delphine_CC_Chiu@Wiwynn.com/)

Test Case:
- When ocp debug card uart button is pressed the position property on
dbus is correct.
