Subject: [PATCH] Restore Snap Supportu

Create new cmake file and alter snapcraft.yaml to build snap builds once more. Due to core22
not supporting qmake yet [1] and Qt not continuing to support qmake[2], this commit moves
Packet Sender snap builds to cmake. In order to not mess with Debian builds (Which use
the existing CMakeLists.txt), a new CMakeLists.txt has been added under a snap directory

The alterations were generated by using qmake2cmake [3] on the .pro file for snap builds,
and then merged under if statements for the existing CMakeLists.txt. I did have to comment out
the git sha generation and add that back manually for the tool to work, as well as specify source root manually.
