pcsx2-tas: Corrections to recording file's header data (#3480)

* The emulator version was hard-coded to PCSX2-1.5.X which is no longer accurate, it is no longer hard-coded and will use the correct version number the same way it is calculated to display in the window title.

* When creating a recording, the game name is preferred over the ISO name. This is determined via the GameDB. When playing back the recording, a simple check occurs to see if the game running is the same one that was used to make the recording. On the playback side, it always only checked with the ISO filename.
