Accomplished using `run-clang-tidy` with `performance-move-const-arg,performance-unnecessary-value-param,modernize-pass-by-value`.

Changed arguments to const references, removed them where inappropriate (e.g. sink parameters). Same with std::move.

Manually reviewed each change to make sure that it makes sense, and do something more appropriate if possible.

This is a continuation of 552b6da. That commit hid sys/boot.bin, but not
disc/header.bin, which is only present for Wii games.

Fixes https://bugs.dolphin-emu.org/issues/13810.

Hide DirectoryBlob boot.bin files from game list

Extracted games contain a boot.bin file that contains the disc header.
These boot.bin files are considered valid volumes by Dolphin, since
Dolphin only checks the disc header to determine if something is a valid
GC/Wii disc. Running them doesn't make any sense, though.

boot.bin files used to not be scanned by Dolphin due to their file
extension, but .bin was added to the list of file extensions to scan for
in 494e2c0. To stop them from showing up in the game list, let's update
the ShouldHideFromGameList mechanism.

In PPCTables.cpp, the code is currently unused so I was unable to test it.

In CustomPipeline.cpp, a pointer to member function cannot be used due to 16.4.5.2.1 of the C++ Standard regarding "addressable functions". https://eel.is/c++draft/namespace.std#6

In Fs.cpp and DirectoryBlob.cpp, these examples used projections in a previous iteration of this commit, but no longer do. Still, they remain in this commit because the PR they would actually belong to is already merged.

In LabelMap.cpp, the code is currently unused so I was unable to test it.

In WiiUtils.cpp, the magic value `1u` was replaced by the constant value `DiscIO::PARTITION_UPDATE`.
