[CI] Add TARGET_ANYGPU

[atamazov]

Add TARGET_ANYGPU and use it here and everywhere.

    expression { params.TARGET_ANYGPU }

Use case: The user wants to avoid usage of any gfx908 nodes. Clearing the params.TARGET_GFX908 flag does not guarantee this because ANYGPU stages occupy the 1st available node, which could be gfx908. Disabling ANYGPU stages is only possible via disabling Vega, gfx908 and gfx90a targets, which is not what the user wants.

With the new flag, the user can clear params.TARGET_GFX908 and params.TARGET_ANYGPU and obtain the desired effect.
