partition_filesystem: Ensure all class members of PartitionFilesystem are initialized

content_archive: Minor changes

vfs: Deduplicate accumulation code in VfsDirectory's GetSize()

gl_state: Temporarily disable culling and depth test.

externals: Update dynarmic to 5a91c94.

address_arbiter: Correct assignment within an assertion statement in WakeThreads()

core/memory, core/hle/kernel: Use std::move where applicable

Previously is_hfs and pfs_header members wouldn't be initialized in the
constructor, as they were stored in locals instead. This would result in
things like GetName() and PrintDebugInfo() behaving incorrectly.

While we're at it, initialize the members to deterministic values as
well, in case loading ever fails.

There's no need to take this by value when it's possible to avoid
unnecessary copies entirely like this.

Gets rid of unnecessary atomic reference count incrementing and
decrementing.

We can just use a generic lambda to avoid writing the same thing twice.

service/prepo: Add missing header guard

externals: update fmt to version 5.1.0

vm_manager: Add missing commas to string literal array elements in GetMemoryStateName()

core/memory: Remove unused function GetSpecialHandlers() and an unused variable in ZeroBlock()

 core: Don't construct instance of Core::System, just to access its live instance

decoders: Fix calc of swizzle image_width_in_gobs.

hle/filesystem: Amend trace log in OpenSaveData() to compile in debug mode

game_list: Make ContainsAllWords an internally linked non-member function

* Virtual Filesystem

* Fix delete bug and documentate

* Review fixes + other stuff

* Fix puyo regression

This was introduced within 4f81bc4e, and
considering there's no comment indicating that this is intentional, this
is very likely a bug.

Without these, this would perform concatenation, which is definitely not
what we want here.

Avoids pointless copies

This makes it a compilation error to construct additional instances of
the System class directly, preventing accidental wasteful constructions
over and over.

This would result in a lot of allocations and related object
construction, just to toss it all away immediately after the call.

These are definitely not intentional, and it was intended that all of
these should have been accessing the static function GetInstance()
through the name itself, not constructed instances.

Previously, we were on 4.1.0, which was a major version behind.

Previously this wouldn't compile, since no such function named
SaveStructDebugInfo() exists.

Touchscreen Support

This function actually depends on no internal class state, so it doesn't
even need to be a part of the class interface.
