Instead of sending ViewEvents once at construction and once at destruction,
it's better to send them when the underlying NSView changes attachment.
The main advantage is that we're about to move the destruction and
emitting of DestroyEvent to the NSView's dealloc method. However, the
dealloc will not be called if user code has a strong reference to it
through a non-empty ViewEvent. By sending an empty ViewEvent when the
view is detached, well-behaving users will remove the strong reference.

Their absense didn't make a practical difference so far, but we're about
to refactor the macOS event processing loop where the pools do matter.

NSView only has events for left, right, and other. Also, the Go side
wasn't actually checking for buttons other than left and right.

Commit c0c25b777 replaced the synchronizing of the display link callback
from a sync.Map to a cgo.Handle. However, the change didn't take into
account the lifecycle issues: a callback may happen just as the cgo.Handle
is freed, leading to a misuse crash.
This change restores the sync.Map synchronization, which avoids the
lifecycle issue.

The windowWillClose callback is too soon to destroy our Window:
at least draw callbacks may be called after windowWillClose but
before the window is gone. This change moves cleanup to the
viewDidMoveToWindow callback where we're sure the NSView is no longer
active.

The Nix version of the macOS toolchain has difficulties compiling
Objective-C modules; disable modules instead of figuring out why.
It also doesn't include any frameworks automatically; add them explicitly.
While here, move suppression of OpenGL deprecation to a GL-specific
file.

We used to track the pressed pointer buttons through the global function
[NSEvent pressedMouseButtons]. However, it's possible that at the time a pointer
press event is delivered, the pointer button is up again. To ensure a consistent
view of the pointer press state, track it through the buttonNumber property on
delivered events.

Add most of the common cursors defined by different systems.
Normalize cursor names to match CSS.
This is API change: some cursor names have changed, and the
underlying type is no longer a string.

This change solves an issue where an editor key press such as
backspace would apply before the IME had a chance to process it.

This change implements reporting of the caret position from Editor, as well
as Windows, macOS, Android support. As a result, the IME composition window
on Windows and macOS is now positioned correctly.

Switching to using a CAMetalLayer as the layer backing our NSView
implementation broke programs such as the opengl example. Somehow, using
ANGLE on top of a CAMetalLayer (but not a CAEAGLLayer) stops resizes
from triggering redraws.
This change invalidates the view in setFrameSize, to force a redraw
and no longer rely on the implicit redraws.

The app and app/internal/wm packages are tightly coupled, requiring
quite a bit of forwarding types, values and constants from the internal
package to export it. Further, no other package imports package wm.
This change merges the two packages.
While here, drop the pre-Go 1.14 SIGPIPE workaround.
