On tegra, when VK_IMAGE_USAGE_COLOR_ATTACHMENT_BIT is set for color image usage
with VK_FORMAT_R16G16B16A16_SFLOAT, dedicated allocation is preferred, but not required.
When using dedicated allocation in this case, we get only a black texture,
and when blitting from that texture, we get a kernel driver error:
gk20a_fifo_handle_mmu_fault_locked:1721 [ERR] fake mmu fault on engine 0, engine subid 1 (hub), client 1 (ce0), addr 0x46cd8aa000, type 15 (poisoned), access_type 0x00000000,inst_ptr 0x212ef3000
Only using dedicated allocation when it is required works around this issue.
This adds some Android support in composition clients,
and fixes the breakage from 2 commits ago.
Thanks to Jakob for finding my error in an earlier version.
