smbios-mdr: Expose Firmware Inventory Information

SMBIOS Type 45 defines the data structure to expose Firmware
Inventory information. Added patch which exposes the same
on the DBus.

Introduced fw-inventory-dbus meson option which by default,
will be disabled. When enabled fw-inventory is exposed to dbus

Introduced expose-firmware-component-name meson option which
by default, will be disabled. When enabled fw-component name is
exposed as dbus object

Tested:
1) No crash is seen when firmware is flashed with change
2) Firmware Inventory information is available under dbus tree
```
