Switch 2: Turing macros, native compute, Ampere shader lowering, native tiling

From changes.patch: the TU104/GA10x MME interpreter (shared macro context for
the process's channels, also on the compute class), native compute with QMD
3.0 dependency scheduling, the Ampere-to-Maxwell shader lowering, native
vertex stream sizes, and the console's GOB swizzle for textures, DMA copies
and the host unswizzle shaders. Switch 2 channels turn all of it on at init.

The lowering is widened for title 4 (all 32 of its programs lower): general
TEX (any dimension/LOD/mask, operand split 1+1/2+1/2+2/4+n, any but consistent
descriptor buffer), cube/array, SULD channel masks, 128-bit STG, indexed IPA,
VOTE, SHFL with any immediate or predicate output, R2P/P2R byte select,
uniform ULOP3/ULEA/UBREV/UFLO.SH/UISETP signed/UMOV URZ, IMNMX cbuf, IADD3
and FFMA uniform operands, FMUL /4 /8 x8, and BSSY/BSYNC/BREAK/WARPSYNC as
no-ops. The capture stops at unmapped memory. EDEN_NX2_SHADER_DUMP dumps every
native program; tools in C:\dev\nx2work test the lowering offline.
