Wa_16015675438 and Wa_18020744125 apply to DG2 using the same action and
conditions. Add both to the oob rules so they are both reported as
active. Note that previously they were not checking by platform or IP
version, hence making them not future-proof.  Those workarounds should
only be active in PVC and DG2, besides the check for "no render engine".

v2: From current WA database, Wa_16015675438 applies to all DG2
    subplatforms except G11. Migrate condition to use subplatform and
    remove G11 from the match (Matt Roper)
