We'd like to remove GioAppDelegate when Gio is embedded with
gogio's -buildmode=archive. Minimize the code in GioAppDelegate.

Recently support was added for multiple top-level windows. Add support
for closing those windows.
macOS only; all others stubbed out.

An interface for scaling dp and sp is overkill, at least for all
current uses. Make it a concrete struct type, and rename it to the
shorter and more precise Metric.

Then, make layout.Context.Now a field, copied from FrameEvent.Now.
API change:
gofmt -r 'gtx.Now() -> gtx.Now'

Recent changes to the macOS threading exposed a problem where a
window's display link may fail to start after being started and stopped
in rapid succession.
Introduce a displayLink type that waits a while after the last stop
request before stopping its display link. That seems to be the way
other projects are using display links.
As a bonus, the new implementation avoids the potentially expensive
overhead of frequent starting and stopping the underlying OS thread.

We're about to move the display link to common Go code. To do that,
we need the redraw logic in Go as well.

Function keys don't have a natural rune representation so switch
Event.Name to be a string to fit "F1"-"F12".
Fixes gio#59

The `gogio` tool adds the `-fmodules -fobjc-arc` flags to the Cgo
C flags. Unfortunately, that masks problems where Cgo packages
accidentally didn't have the flags in their #cgo directives such
as package log.
Move the flags so they're only explicitly mentioned when `gogio`
invokes the host compiler to build the `main.m` shim.
Fix package log to include the missing flags.
While we're here, silence OpenGL ES deprecation warnings on iOS, just
as we do for macOS. The warnings are normally not visible because
the gogio tool suppress output from the go tool.
