Guidelines

1. Rebase before opening a pull request
2. If you are sending several unrelated fixes or features, use a branch and a separate pull request for each
3. If possible try squashing everything in a single commit. This is particularly beneficial in the case of feature merges since it allows easy bisecting when a problem arises

Description

This PR adds a generic HAVE_WAYLAND_BACKPORT flag which when set to 1 will implement fallbacks for wayland compositors (such as those in webOS 1 to 3) which lack support for:

• wl_proxy_marshal_constructor_versioned
• wl_proxy_marshal_array_constructor_versioned
• wl_proxy_get_version
• wl_display_prepare_read
• wl_display_read_events
• wl_display_cancel_read

This has been tested on webOS 1.4 TV (GLES 2 only) device.

wl_surface_set_buffer_scale is only available on V3 of the protocol so that is checked for before using.

GLES 3 is now enabled by default, as my test user has confirmed that it falls back to GLES 2 and they were able to play it.

For legacy sake, I have included an older IPK with GLES 2 and no wayland, just in case any issues arise I can point them at that version to download instead.

It also updates the various github action versions (v1 should point to the latest release for most).
