This reverts commit 94b0e2e5.

preserve_contents proved to be a meaningful optimization. This commit
reintroduces it but properly implemented on OpenGL.

We have to make sure the clear removes all the previous contents of the
image.

It's not currently implemented on Vulkan because we can do smart things
there that's preferred to be introduced in a separate commit.

Fix "Port citra-emu/citra#4956: "Fixes to game list sorting" #3611"

service: Update function tables

{gl,vk}_rasterizer: Add lazy default buffer maker and use it for empty buffers

configuration: Add Restore Default and Clear options to hotkeys

configure_input_player: Use slider to edit modifier scale

vulkan/wrapper: Sort physical devices

decode/arithmetic_half: Fix HADD2 and HMUL2 absolute and negation bits

svc: Re-add MapProcessCodeMemory/UnmapProcessCodeMemory

shader/arithmetic_integer: Fix LEA_IMM encoding

Fix -Werror=conversion and -Wdeprecated-copy issues

frontend/filesystem: Add a trailing separator to the string path

page_table: Remove unused captures

svc: Remove unused variable

shared_memory: Amend doxygen reference

Amends the parameter to match the documentation reference.

Resolves a -Wdocumentation warning with clang.

These were lost in the re-implementation of the virtual memory manager.

Since the VMM refactor, this is no longer used or needed.

Any time the lambda function is called, the permission being used in the
capture would be passed in as an argument to the lambda, so the capture
is unnecessary.

The encoding for negation and absolute value was wrong.
Extracting is now done manually. Similar instructions having different
encodings is the rule, not the exception. To keep sanity and readability
I preferred to extract the desired bit manually.

This is implemented against nxas:
https://github.com/ReinUsesLisp/nxas/blob/8dbc38995711cc12206aa370145a3a02665fd989/table.h#L68

That is itself tested against nvdisasm (Nvidia's official disassembler).

Fix format error in performance statistics

* kernel: memory: Improve implementation of device shared memory.

* fixup! kernel: memory: Improve implementation of device shared memory.

* fixup! kernel: memory: Improve implementation of device shared memory.

service/time: Remove reliance on the global system accessor

CMakeLists: Enable -Wmissing-declarations on Linux builds

Introduce Predictive Flushing and Improve ASYNC GPU

vk_pipeline_cache: Fix unintentional memcpy into optional

The intention behind this was to assign a float to from an uint32_t, but
it was unintentionally being copied directly into the std::optional.

Copy to a temporary and assign that temporary to std::optional. This can
be replaced with std::bit_cast<float> once we are in C++20.

thread: FPCR.FZ is likely not 1 (and FPCR.RMode = TieAway and FPCR.DN = 0)
