### Description
This patch adds support for tearing protocol. To get it working `export WLR_DRM_NO_ATOMIC=1` is probably required.
Setting `ForceTearingRule` is also probably required since surfaces always receive presentation hint 0 (VSYNC) as far as i can tell.
Some apps would send ASYNC hint and tearing will "just work", otherwise it's possible to force specified clients to tear with a rule.
Set rules in the config.h (exact string match):
```
static const ForceTearingRule force_tearing[] = {
{.title = "", .appid = "oni.exe"},
{.title = "", .appid = "hl_linux"},
{.title = "", .appid = "steam_app_210970"},
{.title = "Warcraft III", .appid = ""},
{.title = "", .appid = "gamescope"},
};
```
