Add gpio-presence-sensor

This is to implement the gpio based hw inventory design [1].

There is a new meson option 'gpio-presence' to enable/disable the
daemon.

Summary of the functionality:

- fetch configuration from EM, according to the configuration interface
- the D-Bus interface is
xyz.openbmc_project.Configuration.GPIODeviceDetect
- the configuration represents devices for which presence can be
detected based on gpio values.
- watch gpios for changes
- add/remove the xyz.openbmc_project.Inventory.Source.DevicePresence
interface on the object path based on gpio values.

[1] https://github.com/openbmc/docs/blob/master/designs/inventory/gpio-based-hardware-inventory.md
[2] https://www.kernel.org/doc/html/latest/admin-guide/gpio/gpio-sim.html

Tested: using linux gpio-sim facility, see below

1. create a fake gpio via [2]
2. configure gpio-presence-sensor as per [1]
3. run the gpio-presence-sensor
4. change the value of the gpio previously configured
5. there should be log output (at debug level)
6. the dbus interfaces exposed should appear/disappear as per [1]

A daemon for transferring Viable Product Data (VPD) from device-tree

https://gerrit.openbmc.org/c/openbmc/docs/+/66369

and discussed in this Technical Oversight Forum topic @
https://github.com/openbmc/technical-oversight-forum/issues/38

Tested:
Ensure 'model' and/or 'serial-number' nodes are populated in
/proc/device-tree. Can be hardcoded into platform DTS via
linux-kernel recipe if needed.

'''
After OBMC boot, calling
> busctl introspect xyz.openbmc_project.MachineContext /xyz/openbmc_project/MachineContext

produces the following output:

NAME TYPE SIGNATURE RESULT/VALUE FLAGS
...
xyz.openbmc_project.Inventory.Decorator.Asset interface - - -
.BuildDate property s "" emits-change writable
.Manufacturer property s "" emits-change writable
.Model property s "hpe,dl360" emits-change writable
.PartNumber property s "" emits-change writable
.SerialNumber property s "t5texpl" emits-change writable
...

Note: Writing to one of these properties will update the property on D-Bus without affecting the
underlying device-tree node. An 'updated' event will be fired, so Entity-Manager probes monitoring
a given property would recognize the new value and key off it.

meson: change install_dir to /usr/libexec/entity-manager

We notice a issue that if user accidentally execute fru-device and
terminate it after few second, the xyz.openbmc_project.FruDevice
busname will not exist on dbus, but the status of FruDevice.service is
still active running.

It because sdbusplus changes the behavior of request_name() and it
allows the busname can be replaced by new service. [1]

In order to avoid unexpected behavior by running service binary
accidentally, move the install_dir to /usr/libexec/entity-manager.

Tested result:
- EntityManager is still running normally after the change

dbus: add dbus activation support

Add support for dbus activation of entity manager. Enabling dbus
activation consists of a few simple steps:

- Add an activation configuration in /usr/share/dbus-1/system-services
that maps the dbus service name to the correct systemd service
- Add a service alias for the service to be dbus activated. This
allows dbus activation to be enabled/disabled independently of
whether the service is started at boot by systemd[1].

systemd: install in multi-user.target

Installing in basic.target adds an ordering dependency on every single
unit to entity-manager and fru device. Avoid all these unnecessary
implicit dependencies by installing in multi-user instead.

Testing consisted of booting a rainier bmc to multi-user with any
issues. It should be noted that the rainier target has very few
applications with dependencies on entity-manager and does not presently
use fru-device at all.

entity-manager: systemd: use dbus instead of simple

Use systemd service type dbus instead of simple. This avoids entity
manager client applications that have correctly ordered themselves after
entity manager from attempting to connect before it has claimed a bus
name.

When Type=dbus, systemd automatically adds an implicit dependency on
dbus.socket (so remove the unnecessary dependency on dbus.service).

To build with meson:

Add -Dtests to match de-facto OpenBMC meson usage conventions.

After this patch existing unit tests continue to pass.

One noteable omission is support for subprojects or vendoring. Cmake
support, with subproject vendoring remains.

The OpenBMC CI scripts look for meson.build before looking for
CMakelists so approval of this patch would change the build system
during CI to meson.
