d_a_tag_Lv8Gate OK (#2079)

* Initial pass of d_a_tag_Lv8Gate, lots to do still

* Another decomp pass, most are close but several nonmatching still

* All functions match, needs final cleanup pass

* Decomp OK

* Format pass and some minor cleanup

* Another minor cleanup pass

* Forgot to format, updating progress doc

* Removing asm files

* Removing empty ctor (not needed for match)

* Implementing PR suggestions

* Tiny bit more cleanup based on PR feedback
