meson: switch config.h to config.hpp

Enable a transition of this file from C to C++ so that we
can use C++ constants instead of #defines in future commits.

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.

Enable group gpio configuration

This change adds support to configure single
as well as group gpio config using a single api(configGroupGpio()).
This change is introduced to support the button/input
interfaces which has multiple gpios associated with them.

As an improvement reading of gpio def json file is
done once in main function rather than reading it
everytime before creating the button interface object.

Do dummy GPIO reads on startup

Do a read of all of the button GPIOs after they are configured
but before the sd_event handling has been set up to prevent
a spurious sd_event callback as soon as the event loop starts.

Without these, a button released signal gets sent every time
the application starts.

Tested: Saw that the spurious callbacks went away.

This is how a system implementer can specify which
