ed1bdf9b1a gl: Fix crash in cocoa due to race in gst_gl_context_activate()
We create a new context in `gst_gl_context_create_thread()` and then
activate it on the current thread. Thereafter we assume that the
current thread continues to be the active thread for that context and
call `gst_gl_context_fill_info()` which asserts that the current
thread is the active thread.

However, if at the same time a different thread calls
`send_message_async()`, it will call into
`gst_gl_window_cocoa_send_message_async()` which will schedule the
message to be invoked using GCD. That anonymous function will also
call `gst_gl_context_activate()`, which creates a race, which can lead
to:

```
gst_gl_context_fill_info: assertion 'context->priv->active_thread == g_thread_self ()' failed
```

Fix it by using `gst_gl_context_thread_add()` to invoke `fill_info()`
on the context.

19603248c2 gl: Mark gst_gl_context_new_wrapped() return value as nullable
If a GL context is requested for which no API support is compiled in
then `NULL` is returned.

Also remove a useless `NULL` check: `g_object_new()` can't possibly
return `NULL`, ever.

a1f30f5b9b gl/context: disable timer queries for ARM Mali-G52
Performing a timer query with a default framebuffer that is incomplete
(from using a surfaceless context) will produce GL errors.  Disable the
timer query on this platform to avoid the errors.
