Support more more formats for input attachments

- sRGB formats - BGRA and ARGB_PACK32 formats - 1 and 2 channel 16 bit formats 16bit float formats still don't work due to missing support elsewhere Test: dEQP-VK.renderpass.suballocation.formats.* Bug: b/131171141 Change-Id: I8f659a894c671552b4061890f299d65992fc085c Reviewed-on: https://swiftshader-review.googlesource.com/c/SwiftShader/+/30031Tested-by: 's avatarChris Forbes <chrisforbes@google.com> Reviewed-by: 's avatarNicolas Capens <nicolascapens@google.com> Kokoro-Presubmit: kokoro <noreply+kokoro@google.com>
