This is effectively a revert of 60e4cca934, which
seems to have caused flickering problems on some versions of Windows.

The gioui.org/commit/74407a50d598bfd27e8f8e48b6832cc5df04de77
added a NewImageOp constructor that always copies the supplied
image. It does that for two reasons:
First, the image.Image reference is used in the image=>texture
map of cached textures. Without a copy, we wouldn't detect a
modified image even if a new ImageOp was created.
Second, we don't want the program to touch the image while the GPU
is uploading it.
The second reason was removed in a previous change that blocks
FrameEvent.Frame until we're done with the operations, including
uploading images to the GPU.
The first reason is easily fixed by using a unique per ImageOp,
as pointed out by Alessandro Arzilli.
This change switches to using the unique key. Alessandro's patch
avoids the copy when possible.

It was already true that the GPU wouldn't touch the frame after
calling GPU.Draw. This change makes FrameEvent.Frame block until
GPU.Draw is complete.

Now that we use tip due to breaking changes in Go's JS APIs, let's
replace our hacky cleanup list code with 1.14's upcoming
testing.T.Cleanup.
Adding more deliberate uses of tip would ususally be best avoided, but
these will only affect developers working on gio's tests, not regular
users of gio.
While at it, remove some debug t.Logf calls I forgot to remove.

This means we can deduplicate some of the logic, and keep it all in one
place.
Start expanding the logic too; the tests are slow, so they should be
skipped on 'go test -short'. The ones we have so far all run in a matter
of seconds on an average laptop today, but future tests will probably
require heavier work like wine or kvm.

When the control key is pressed, clear event.state bits before calling
Xutf8LookupString in order to get the unmodified key name. This allows
proper handling of all keys in combination with ModCommand.
`key.Event.Name` is however layout dependent. Client code should be
careful about this when picking key shortcuts like CTRL-'+': on a QWERTY
keyboard, only CTRL-'=' and CTRL-SHIFT-'=' are generated when pressing
the '=' key of the top row. The keypad '+' key generates events with
`Name = '+'` as expected.

In an earlier commit, we made it possible to run the e2e tests with the
race detector enabled everywhere via GOFLAGS=-race go test.
However, that's not at all standard; most users will simply use 'go test
-race'. Moreover, having 'go test -race' run the test program with the
race detector, but not the e2e gio app, is a bit useless.
Instead, have the tests detect when they run with the race detector, and
enable the race detector in the test app too. As before, the JS test is
skipped whenever -race is used.
This also means we can test with -race in the same way in each of the
modules, which simplifies CI.

Before this change, Gio tries hard to come up with a reasonable UI scale
factor on desktop OSes derived from the physical dimensions and
resolution of connected monitors. Gio also attempts to detect the user
specified system UI scale and apply it.
However, all that is complex and misguided:
- The UI scale should not depend on whatever monitor is connected at
program startup - For multiple monitors, it's unclear which one to base
the scale off. - Applying both a monitor derived scale *and* the user
specified scale is wrong, because the user scale is relative to some
fixed scale, not Gio's derived scale. - With an automatic scale, Gio
does not respect user preference and will not have a similar scale to
other programs on the desktop.
Get rid of the the automatic UI scale detection and rely only on the
user scale.

Right now, we can only run the e2e gio app with -race, not without
-race, because the flag is hard-coded in the tests.
The reason for this change was that 'GOFLAGS=-race go test' would fail
with the JS test, since js/wasm doesn't support the race detector. Fix
that by skipping the JS test when -race is used.
Now, we can run multiple levels of -race:
go test # no -race at all
go test -race # -race for the tests, not the e2e gio app
GOFLAGS=-race go test # -race for everything (best-effort)
To detect the race detector being on, we use a file with a build tag.

It's not possible to set GOFLAGS=-race because some programs are
built for webassembly where -race is not supported.

Clicking doesn't quite work yet, but everything else does. We use a
custom sway config to ensure that it's a minimalist setup with no bar or
borders, like the other drivers.
The generic test now adapts to the window's real size when running in
non-headless mode, since tiling window managers resize some drivers like
sway. The default headless mode still expects the exact size that we
specify, as no real windows are at play.
While at it, clean up some now unused code from the x11 file.
