[ANGLE] Lose Metal-backed contexts
https://bugs.webkit.org/show_bug.cgi?id=257584
rdar://109176858
Reviewed by Dean Jackson.
ANGLE provides a mechanism for determing if there has been a error with the
renderer backend via the DisplayImpl::testDeviceLost() and
ContextImpl::getResetStatus() APIs. The Metal renderer backend never signals an
error.
Metal provides a status on command buffer completion to signal if there has been
an error when processing a MTLCommandBuffer. This patch adds experimental
support for losing the context when this status signals there was an error. The
context can't be recovered once it is lost and needs to be recreated.
The feature is available when ANGLE_METAL_LOSE_CONTEXT_ON_ERROR is defined when
compiling ANGLE.
