program_metadata: Set a default resource size when a NPDM is not present

program_metadata: Explicitly specify copy/move operators/functions

lm: Resolve -Wextra-semi warning

acc/lbl: Remove unused variables

aes_util: Make use of std::span

Sets a default size of 0x1FE00000 bytes (510 MiB) for the system_resource_size when a NPDM is not present.

emu_window: unsigned -> u32

This is only a 2-tuple, so it can be converted over to the std::pair
class.

This is more concise and consistent with the rest of the codebase.

Allows us to simplify the interface quite a bit as it will handle
contiguous sequences for us.

Avoids unnecessary default construction of an entry in cases where no
entry exists before overwriting the created entry.

We can perform the lookup and then do the contains check by checking the
end iterator. The benefit of this is that if we *do* find an entry, then
we aren't hashing into the map again to find it.

We can also get rid of an unused std::vector temporary while we're at
it.

Resolves a trivial warning with clang.

The generation of the copy assignment operators are deprecated on being
generated when a user-provided destructor is present.

We can explicitly specify that we desire this behavior to keep the class
forward compatible with future standards.

yuzu_cmd: Remove unused resource.h

cmake: Download Boost from ext-linux-bin if inadequate local version

Building SDL2 from externals is incompatible with Conan's version of
libiconv, a requirement of Conan's Boost package. Solution is to use the
same Boost package in use by the linux-fresh container. This tells CMake
to download boost_1_75_0.tar.xz from yuzu-emu/ext-linux-bin at CMake's
configuration step, much the same way Qt and FFmpeg are downloaded for
Windows.

Also makes DownloadExternals.cmake cross-platform. Although the CMake
code is not entirely specific to Linux, only Linux has Boost libraries
available at ext-linux-bin, whereas there is no equivalent Boost package
for Windows at ext-windows-bin. caveat emptor

cmake: Fix FFmpeg external usage and cleanup 

time: Fix GetClockSnapshotFromSystemClockContext

If SDL2 is not found, the error is handled by falling back to externals.
No need spill the full warning at the find_package if it's going to be
handled later, so add QUIET to it.

Sets find_package(FFmpeg) to QUIET instead of REQUIRED. This allows
using the FFmpeg external in cases where there is no suitable installed
version of FFmpeg.

Also fixes a bug where multiple CMake configures causes FFmpeg_LIBRARIES
to concatenate on itself, producing cyclical dependencies. Unsets the
variable before building it in the foreach loop.

Fixes FFmpeg_INCLUDE_DIR not including the headers generated at run
time.

log/backend: Make use of erase_if

texture_cache/util: Fix src being used instead of dst within DeduceBlitImages case

cmake: Use SDL 2.0.14 and fix scope issue

We can also avoid redundant constructions of the same string repeatedly.

Same behavior, but less verbose.

general: Write buffers before pushing raw arguments

npad: Remove duplicated class member variable

arp: Prevent potential uninitialized read of launch member variable

This line can only ever be reached if src is null, so dereferencing it
here is a logic bug that slipped through.

Instead, we dereference dst instead which is guaranteed to be valid.

For consistency with the rest of the service implementations

Reduces some verbosity and centralizes the function details in one spot.

If anything happened to call arp functions in the wrong order and called
IRegistrar's Issue function before SetApplicationLaunchProperty, we'd
read from an uninitialized ApplicationLaunchProperty instance.

Instead, we can always initialize it so if this does happen, then the
outcome of doing such a thing is at least consistently reproducible.

ControllerBase already has a System reference that can be accessed from
this class, so we can get rid of this to make the class layout a little
more straightforward.

This removes an incorrect alignment usage and corrects the positions of the popped parameters.
