...by removing the entire adjustedFormat() helper.
Qt Quick has never used this, which indicates it is not that
useful. Same goes for Qt Multimedia or Qt 3D. Ensuring depth and
stencil is requested is already solved by using
QSurfaceFormat::setDefaultFormat() or by adjusting the formats
everywhere as appropriate.
The helper function's usages are in the manual tests that use it as a
shortcut, and in the GL backend itself. Remove it and leave it up the
client to set the depth or stencil buffer size, typically in the
global default surface format. (which in fact many of the mentioned
manual tests already did, so some of calls to
window->setFormat(adjustedFormat()) were completely unnecessary)
By not having the built-in magic that tries to always force depth and
stencil, we avoid problems that arise then the helper cannot be easily
invoked (thinking of widgets and backingstores), and so one ends up
with unexpected stencil (or depth) in the context (where the GL
backend auto-adjusts), but not in the window (which is not under
QRhi's control).
It was in practice possible to trigger EGL_BAD_MATCH failures with the
new rhi-based widget composition on EGL-based systems. For example, if
an application with a QOpenGLWidget did not set both depth and stencil
(but only one, or none), it ended up failing due to the context -
surface EGLConfig mismatches. On other platforms this matters less due
to less strict config/pixelformat management.

Even though there is no D3D-specific logic in the windows platform
plugin, meaning a QWindow with either OpenGLSurface or VulkanSurface
(or anything really) is DXGI/D3D-compatible, it now looks like it is
beneficial, and more future proof, if there is a dedicated surface
type.
As the linked report shows, there are OpenGL-specific workarounds
accumulated in the platform plugin, while not being clear if these
are relevant to non-OpenGL content, or if they are relevant at all
still. (and some of these can be difficult/impossible to retest and
verify in practice)
When D3D-based windows use the same surface type, all these are
active for those windows as well, while Vulkan-based windows have
their own type and so some of these old workarounds are not active
for those. To reduce confusion, having a dedicated surface type for
D3D as well allows the logic to skip the old OpenGL workarounds,
giving us (and users) a more clear overall behavior when it comes
to OpenGL vs. Vulkan vs. D3D.
The change is compatible with any existing code in other modules
because any code that uses OpenGLSurface for D3D will continue to
work, using the new type can be introduced incrementally.

For historical reasons we use build and release instead of create and
destroy. This becomes confusing now that more modules in Qt start taking
QRhi into use. Migrate to the more familiar naming, so those who have
used QWindow or QOpenGLContext before will find it natural.

Revert surfacePixelSize() to be a getter only. With Metal this will
mean returning the "live" layer size (and so not the
layer.drawableSize), which is in line with what we expect with other
backends.
Instead, we leave it to the swapchain's buildOrResize() to "commit"
the size by setting drawableSize on the layer. With typical
application or Qt Quick logic this ensures that layer.drawableSize is
set once and stays static until we get to process the next resize - on
the rendering thread.
This of course would still mean that there was a race when a client
queries surfacePixelSize() to set the depth-stencil buffer size that
is associated with a swapchain. (because that must happen before
calling buildOrResize() according to the current semantics)
That can however be solved in a quite elegant way, it turns out,
because we already have a flag that indicates if a QRhiRenderBuffer is
used in combination with (and only in combination with) a
swapchain. If we simply say that setting the UsedWithSwapChainOnly
flag provides automatic sizing as well (so no setPixelSize() call is
needed), clients can simply get rid of the problematic
surfacePixelSize() query and everything works.

All APIs are private for now.
Shader conditioning (i.e. generating a QRhiShader in memory or on disk
from some shader source code) is done via the tools and APIs provided
by qt-labs/qtshadertools.
The OpenGL support follows the cross-platform tradition of requiring
ES 2.0 only, while optionally using some (ES) 3.x features. It can
operate in core profile contexts as well.
