Title:
  [SRU] Support isdv4-aes stylus group and multiple AES stylus
  definitions

Status in OEM Priority Project:
  New
Status in libwacom package in Ubuntu:
  New

Bug description:
  [Impact]

   * There are lots of stylus couldn't be used on Lenovo's platform, our
  OEM customer request to support ThinkPad P15 Gen 1, ThinkPad X1 Yoga
  Gen5, ThinkPad P1 G3.

   * I reviewed and tested the below patches from upstream. It could
  support the stylus very well on P15, P1 or X1 Yoga.

   * a864679 - Add multiple AES stylus definitions 
     I applied into libwacom2 1.3-2ubuntu1, no errors.

   * 8652aa3 - Add isdv4-aes stylus group to all AES sensors
    I tried to apply this patch, but there are not 'data/isdv4-48ca.tablet' and 'data/isdv4-48ce.tablet', it failed for these two files.

   * ba02abf - Add ISDv4 51e9 (Lenovo ThinkPad P15 Gen 1) (#325)

  [Test Plan]

   * Need your laptop have AES stylus, check the pen setting at gnome-
  control-center when the pen touch the screen. It could not
  set/customize the stylus, such as the second button as right click.

   * After updated the new packages with these patches, you could
  customize the stylus at gnome-control-center.

  [Where problems could occur]

   * It only changes the data/ parts to support more stylus from
  upstream, so it's low risk.
