Don't evict CompositorFrames based on the number of SharedBitmaps

We used to keep the file descriptors of SharedBitmaps open and therefore
evicting frames would help avoid reaching the limit of max number of
open file descriptors. However, now we just close the file descriptor
after it is mapped to virtual memory and evicting frames isn't necessary
anymore.

Move frame eviction code to components/viz/client

Move frame eviction code to components/viz/client to make it accessible
in the clients and prevent further introduction of dependency on service
code.
