Arm backend: remove flag from Vk pipeline session (pytorch#19669)

The flag VK_PIPELINE_CREATE_2_FAIL_ON_PIPELINE_COMPILE_REQUIRED_BIT
means
"Do not perform expensive synchronous compilation during this call"

If Vulkan detects that this is needed, it instead
throws an error. We can skip this pre-caution.
