v_mad_f32, v_mac_f32, v_madak_f32 and v_madmk_f32 exist only on gfx10.1,
so the RDNA2 oracle can't measure them. Measured on gfx1010 (RX 5700 XT)
in wave32 at IEEE 0 and 1, f32 denormal modes 0 to 3 and round modes 0
to 3, and in wave64, they round the product before the add, flush f32
sources, product (tiny after rounding with an unbounded exponent) and
result in every mode, and choose NaN results like the fma forms.
The behaviour stays left to the driver: translating it on every lane
cost about 15x main on the RX 5700 XT and 23x on an RTX 3070, and a
branch around the exact path still about 6x, so the lowering waits for
the SPIR-V float controls of #981.

Adds what testers reported in the Q&A thread and what our own runs
showed: confirming the GPU and the cache state, AC power and refresh
rate, the Windows exit code of an uncaught exception, Windows session
and scheduled-task start, Unity module placement and the MinGW DLLs,
a section on measuring performance, and the report fields.
Drops APS5_NO_MOUSE_CAPTURE, which main no longer has.

A report names the GPU as the log's `Selected GPU name=` line shows it, since AnyPS5 can fall back to llvmpipe without presentation support or pick another adapter on Windows (suggested by odntht on #6627).

Draft guide for running a title on AnyPS5: the build and conversion steps,
the environment variables to set for each run, what to read in the log and
the exit code, how to tell a stall from a crash, Windows-specific notes, and
what to include when reporting a result. Maintainers are asked what they need
from it in the Q&A discussion linked from the page.

Copy the guest TZ under the guest environment lock so a concurrent setenv
cannot free it while it is read, and hold one lock across the zone switch
and the conversion so the fields of two zones are never mixed. Document the
host rejection, Windows zone name and stale tm_zone limits.
Guest setenv, putenv and unsetenv only change the guest environment, while
the time conversions read the host TZ, so a guest that set TZ and called
tzset still got host local time. Copy a changed guest TZ to the host before
each local conversion and call tzset again.
A pipelined draw read its index buffer from guest memory at commit time,
after the packets behind it had run, so a later dispatch's deferred
storage-image write-back could land in the bytes first. Stellar Blade
recycles its full-screen quad's index buffer for a 66x66 image when the
menu loads, and aborted with "vertex fetch exceeds descriptor record count".
Deferred write-backs now wait while a queued draw still holds a read of the
range. APS5_NO_QUEUED_DRAW_READ_ORDER=1 restores the old order; [draw]
reports held read ranges and stores.
