147073a5a0 file-sys: Make use of std::string_view where applicable
Same behavior, but makes the interface more flexible and allows
non-std::string instances to be used with it.

gl_shader_disk: Make use of std::nullopt where applicable (#5293)
Some implementations can use the std::nullopt_t constructor of
std::optional to avoid needing to completely zero out the internal
buffer of the optional and instead only set the validity byte within it.

e.g. Consider the following function:

std::optional<std::vector<ShaderDiskCacheRaw>> fn() {
    return {};
}

With libc++ this will result in the following code generation on x86-64:

Fn():
  mov     rax, rdi
  vxorps  xmm0, xmm0, xmm0
  vmovups ymmword ptr [rdi], ymm0
  vzeroupper
  ret

With libstdc++, we also get the similar equivalent:

Fn():
  vpxor   xmm0, xmm0, xmm0
  mov     rax, rdi
  vmovdqu XMMWORD PTR [rdi], xmm0
  vmovdqu XMMWORD PTR [rdi+16], xmm0
  ret

If we change this function to return std::nullopt instead, then this
simplifies both the code gen from libc++ and libstdc++ down to:

Fn():
  mov     BYTE PTR [rdi+24], 0
  mov     rax, rdi
  ret

Given how little of a change is necessary to result in better code
generation, this is essentially a "free" very minor optimization.

7f8151b9b9 savedata_archive: Make GetFreeBytes return a more accurate value
Previously, we were returning a value that was way too big, causing an integer overflow in Fractured Souls.
According to wwylele, the biggest oberserved save size for 3DS is 1MB, so this new value should leave plenty of room, even if games use a bigger size.

memory: Make getter functions const qualified where applicable (#5251)
Many of these functions are capable of being used within const contexts,
so we can apply the const qualifier in some cases and add const based
overloads for others, which makes the interface a little bit more
flexible and const-correct.

core/memory: Make use of std::move in Entry::operator= (#5233)
* core/memory: Amend unusual return value of operator=

operator= usually returns a reference to this. Given there's no comment
explaining why void was used, this can be assumed to be an oversight.

* core/memory: Make use of std::move in Entry::operator=

Same behavior, minus the need for an atomic reference count increment
and decrement (since MemoryRef contains a std::shared_ptr).

12279b22cc gl_resource_manager: Make use of noexcept on move assignment and move constructors
Several standard constructors generally check if objects can be moved in
a non-throwing manner (usually via std::move_if_noexcept) to preserve
its exception guarantees. This means that if these were used with
certain containers any reallocations internally would cause resource
churn, as copies would be necessary instead of moves.

This way, if they're every used in that manner, the right behavior is
always performed.
