caopengllayer: fix using layer outside of main thread
When stopping the playback, vout_display_t destructor will call the
[VideoView vlcClose] which references the backing CALayer through [self
layer]. This function is not thread-safe and should only be called from
the main thread, leading to reports and crashes when using the main
thread checker.
Instead, since we allocate the layer and references it from the
vout_display_t implementation, just send the vlcClose message on the
stored layer directly. Since it's only used to pass from the vd from the
view to the layer, and it's initialized from a dispatch_sync() in the
Open() function, there won't be race de-initializing them in a
non-synchronized fashion like done in this commit.
Fixes #27513
