feat(libc): implement sceLibcBacktraceSelf on Windows - #2

The expected count in the failure message of the staged clear sampled
read test is Threads * 4u + SampleTexelBytes, a std::size_t, but was
formatted with %u. On LP64 hosts that is the only -Wformat warning in
the tree, and the message would print the wrong value.

reachingWriter followed only fall-through and direct branches, so a V#
load on a path that reaches the loop through an s_setpc_b64 jump the
control flow analysis resolves was not seen, and another load could be
taken as the only writer. The walk now follows those jumps. It also
fails at s_call_b64 targets, whose callers it does not follow, instead
of walking from a function entry into the code above it.

…in pointer image tables

…d test key dynamic

The PS5 module checks max_image_width - 1 > 999999 in
scePngDecQueryMemorySize and scePngDecCreate and returns
0x80690003 (INVALID_PARAM). This returned 0x80690002 (INVALID_SIZE)
and accepted a width of 1000001.

sceUserServiceInitialize reads the thread priority from the first int
of its parameters, and sceUserServiceInitialize2 takes it as its
argument. A PS5 returns 0x80960005 for a priority outside 0x100 to
0x2FF, and 0x80960003 when Initialize2 is called on an initialized
service, where this returned success.

A draw whose vertex shader exports the render target array index into a
color view of several slices of a 2D array target was refused. The view
now renders layers lastSlice - slice + 1 through a 2D array attachment
view of the array's resident image starting at its first slice, and the
draw marks every rendered slice dirty. A view of several slices of a
surface that is not a 2D array is still refused, as is a layered draw
without the array's resident image.

AI-assisted: yes

…of its view's slices

A layered draw into a color view of slices 0 to 5 of a 2D surface whose
CB_COLOR_ATTRIB3 declares one slice was refused. The CB clamps the
render target array index to the view's SLICE_MAX, not to the surface's
slice count, so each layer is written one slice pitch further on.
PPSA01317 renders a 512x512 cube map this way. Such a view now renders as
a 2D array of the view's last slice + 1 slices.

AI-assisted: yes

…the volume layer guard

The resident image of a 2D array color view only compared the view's own
slice offset with the image's layer pitch, which is trivially equal for
slice 0. Every slice of the array image is now checked against the slice
size DecodeColorBuffer offsets the view by. AttachmentView again requires
layer 0 for a 3D target, as it did before layered 2D array views.

AI-assisted: yes

A vertex shader exporting the render target index draws one value per
layer into a CB_COLOR_VIEW of slices 1 to 3 of a four-slice 2D array and
into slices 0 to 2 of a surface of one slice. After the write-back every
slice of guest memory must hold its layer's value, and the slices
outside the view (slice 0, and slice 3 of the one-slice surface) their
initial bytes.

AI-assisted: yes

sceLibcBacktraceGetBufferSize and sceLibcBacktraceSelf threw on Windows.
Guest modules there are unwound from their DWARF tables (.ehfram), which
the Windows stack walkers do not read, so the frames come from this
libc's own _Unwind_Backtrace, as boykopovar#7083 also does, and each return
address is mapped to its module with GetModuleHandleExW. The record
layout and the frame order are the Linux ones.

GuestBacktrace now runs on Windows too: the module and function of an
address come from GetModuleHandleExW and RtlLookupFunctionEntry there,
and from dladdr on Linux.
