[ Impact ]

 * No information is shown on the Gnome System About page. This results in a 
   not-well versed person to now know what CPU their system is running on.

 * This is because ARM systems do not offer an interface for readable names as 
   x86_64 does. The readable names have to be inserted by some means of mapping 
   the CPU implementer and part to a readable. Other programs such as lscpu do
   this by inserting a mapping table in the code. This patch extends the created
   data structure from libgtop by executing lscpu and parsing the relevant
   information. Only the requested readable name is added to the libgtop
   structure.

[ Test Plan ]

 * Open the About page on a gnome ubuntu system - if you are on an arm64 system 
   the `Processor` field is empty.
 
 * With the patch applied the Processor field is now filled with the readable 
   name of the CPU and the amount of the cores.

[ Where problems could occur ]

 * This patch touches the system information gathering for the cpu. So any 
   program relying on this structure might end up with invalid data if they are 
   relying on a fixed size. In the case of the about page it would show no 
   information.

[ Other Info ]

 * There is currently a merge request open for this change upstream, but 
   upstream is blocked due to problems in the ci/cd pipeline:
   https://gitlab.gnome.org/GNOME/libgtop/-/merge_requests/51

 * The patch has gone through a first review already

Title:
  AArch64: Processor Name in GNOME System Info is blank

Status in libgtop2 package in Ubuntu:
  New

Bug description:
  Per upstream bugs https://gitlab.gnome.org/GNOME/libgtop/-/issues/60
  and https://gitlab.gnome.org/GNOME/libgtop/-/issues/66, libgtop (used
  by GNOME and Xfce) doesn't know how to read the processor name on
  non-x86 systems.

  /proc/cpuinfo which it uses doesn't contain the processor name on
  AArch64 systems. Instead it should read output from `lscpu`, or the
  SMBIOS processor table.
