Some draws do write depth but cannot contribute to LRZ during the BINNING pass
e.g. when fragment shader has "discard" in it, however they can contribute to
LRZ during the RENDERING pass via LRZ feedback meachanism. This may allow the
draws that follow to depth test against the updated LRZ, this is especially
important if such "bad" draws were at the start of the renderpass.
LRZ feedback happens during the RENDERING pass when LRZ_FEEDBACK_ZMODE_MASK
is set, if draw has a6xx_ztest_mode that has corresponding flag set in
LRZ_FEEDBACK_ZMODE_MASK - its depth values would be used for feedback.
LRZ feedback alongside with LRZ testing also works during sysmem rendering.

The front-page of the docs is currently fairly intimidating, by diving
into details rather abruptly. Let's try to make it a bit easier to
navigate t by moving the details to their own articles, but linking them
from the front-page.

When using Freedreno's RD output facilities, enable prefixing any output or
trigger file with the string specified in the FD_RD_DUMP_TESTNAME environment
option. This is similar to how the TESTNAME env can be used with libwrap to
provide a more descriptive name for the output RD file.
These prefixes can be quite long, e.g. the longest test case name in Vulkan CTS
is above 250 characters. For that reason the output name string in the
fd_rd_output struct is now allocated on the heap, and any path building using
the output name has its on-stack string buffer enlarged.

A seperate meson project with mesa as a subproject was required to
compile the generate_rd executable for replaying rddecompiler
generated source. That approach was overly complicated, now the
generate_rd executable is now compiled as a part of building the
freedreno tools with a blank generate-rd.cc file that can be replaced
with the source generated by rddecompiler.

Provide fd_rd_output facilities which enable constructing RD dumps that are
stored into gzip-compressed output. This matches the default behavior of
libwrap. Enabling and adjusting the behavior of functionality is done
through the FD_RD_DUMP environment variable.
Integration into Turnip's MSM backend is covered, replacing the previous
RD dump that was enabled through TU_DEBUG=rd. That debug option still
works and is the same as using FD_RD_DUMP=enable.
By default the dumps are created for each submission, using the provided
submit index. FD_RD_DUMP=combine enables gathering dumps for submissions
for the given logical device into a single file.
In the Turnip integration, FD_RD_DUMP=full will force dumping contents of
any buffer object. Additionally, with that option enabled any previous
submit will be waited on.
Specifying FD_RD_DUMP=trigger sets up a trigger file that can be used to
activate dumping manually. Writing zero or some non-integer value to the
file will disable dumping. Writing a positive integer value to it will
enable dumps for that many future submissions. Writing -1 to it will enable
dumps until disabled.
