Celegans12 6e34e8614e feat(agc): implement sint storage images through uint views
Storage images of a SINT format threw "storage image descriptor uses
an unsupported format"; only write-only 32_SINT was accepted.

The recompiler now writes 16_SINT, 8_8_SINT, 32_SINT, 16_16_SINT,
8_8_8_8_SINT, 32_32_SINT, 16_16_16_16_SINT and 32_32_32_32_SINT
storage images with the Uint numeric class. 8- and 16-bit components
are saturated (EmitFormatStoreComponent) and 32-bit ones stored
unchanged, as measured on RDNA2 (gfx1035); image_store_pck stores
32-bit components unchanged too. The driver binds these surfaces
through a cached view of the same-size UINT format.

8_SINT, 32_32_32_SINT, the packed SINT formats (11_11_10, 10_11_11,
2_10_10_10, 10_10_10_2), D16 stores, packed stores of 8- and 16-bit
components and atomics other than 32-bit ones on 32_SINT and 64-bit
ones on 32_32_SINT still throw. New test: agc_driver_image_store_sint,
with DST_SEL X,Y,0,1 on the two-channel formats, as with X,Y,Z,W the
hardware writes channel 1 from the W data slot (TechnicalDebt).
