loader/wayland: Move acquisition time tracking into perfetto flows

Browse Source 
We only use the acquisition time for calculating latency for perfetto
tracks later, and the acquisition time should ideally be the start of the
perfetto flow.

This has been more or less true with very small error margin for vk wsi,
but the wayland EGL buffer handling is a lot more complicated. Moving the
time check into the flow start will make re-using this code for EGL much
simpler.
