nir/vtn: Implement printf opcode in terms of intrinsic (v9)

Browse Source 
[airlied: rebase fixup types]

v2: add support for storing strings in a sideband storage,
just store the index in print buffer.

v3: move the format strings into the nir shader as well

v4: simplify the write constant string + explicit sizes
move printf cap definition.

v5: just parse the format string to find string specifiers
using util code.
add vtn_fail_if if we can't get the correct type.

v6: use ralloc + avoid instr handler for srcs > 5

v7: use a packed struct 4 bytes align all of it

v8: simplify constant copy

v9: rework to use a single string and common string
extract code, (Jason)
