  [WPE] Add explicit fence support for wayland
https://bugs.webkit.org/show_bug.cgi?id=276818

Reviewed by Miguel Gomez.

We are adding support to pass fence from the WebProcess to the wayland
server to avoid stopping the pipeline in the CPU. This is the initial
implementation, we are using the protocol
linux-explicit-synchronization-unstable-v1 and we plan to add support
for new protocols and DRM fences in the future.

The compositor generates a fence for the frame that is used to create a
synchronization point in the command queue and passed to the wayland
server. Also we receive the fence for the buffer usage from the wayland
server that we associate to the buffer and pused to the command queue
before using the buffer.

The patch adds the parameters to the messages in the IPC communication
between WebProcess and UIProces and methods to handle both fences.
