Replace &vec[0] with vec.data()
When the vector is empty, using `&vec[0]` involves undefined behaviour. While that works fine most of the time, Flatpak builds aborted on a failed `__builtin_expect`.

I searched for such occurences across the codebase with the regex `(?<!&)&\w+\[0\]` and fixed those that would potentially cause issues.

41f42d8df3 common: Silence two discarded result warnings
These are intentionally discarded internally, since the rest of the
public API allows querying success. We want all non-internal uses of
these functions to be explicitly checked, so we can signify that we
intentionally want to discard the return values here.

6ed4431d8b file_util: Early-exit in WriteArray and ReadArray if specified lengths are zero
It's undefined behavior to pass a null pointer to std::fread and
std::fwrite, even if the length passed in is zero, so we must perform
the precondition checking ourselves.

A common case where this can occur is when passing in the data of an
empty std::vector and size, as an empty vector will typically have a
null internal buffer.

While we're at it, we can move the implementation out of line and add
debug checks against passing in nullptr to std::fread and std::fwrite.

fb941c56d8 common/file_util: Allow access to files on network shares
On Windows, network shares use paths like \\server\share\file which were
being broken by FileUtil::SanitizePath() removing double slashes.

Changed the code in SanitizePath to permit a double-backslash if it
occurs at the start of a filepath (on Windows only).

common: Port some changes from dolphin (#5127)
* IOFile: Make the move constructor and move assignment operator noexcept

Certain parts of the standard library try to determine whether or not a
transfer operation should either be a copy or a move. The prevalent notion
of move constructors/assignment operators is that they should not throw,
they simply move an already existing resource somewhere else.

This is typically done with 'std::move_if_noexcept'. Like the name says,
if a type's move constructor is noexcept, then the functions retrieves an
r-value reference (for move semantics), or an l-value (for copy semantics)
if it is not noexcept.

As IOFile deletes the copy constructor and copy assignment operators,
using IOFile with certain parts of the standard library can fail in
unexcepted ways (especially when used with various container
implementations). This prevents that.

* fix various instances of -1 being assigned to unsigned types

* do not assign in conditional statements

* File/IOFile: Check _tfopen_s properly

* common/file_util.cpp: address review comments

core, citra_qt: Implement a save states file format and slot UI
10 slots are offered along with 'Save to Oldest Slot' and 'Load from Newest Slot'.

The savestate format is similar to the movie file format. It is called CST (Citra SavesTate), and is basically a 0x100 byte header (consisting of magic, revision, creation time and title ID) followed by Zstd compressed raw savestate data.

The savestate files are saved to the `states` folder in Citra's user folder. The files are named like `<Title ID>.<Slot ID>.cst`.

Port yuzu-emu/yuzu#2511: "common/file_util: Minor cleanup" (#4782)
* common/file_util: Make IOFile's WriteString take a std::string_view

We don't need to force the usage of a std::string here, and can instead
use a std::string_view, which allows writing out other forms of strings
(e.g. C-style strings) without any unnecessary heap allocations.

* common/file_util: Remove unnecessary c_str() calls

The file stream open functions have supported std::string overloads
since C++11, so we don't need to use c_str() here. Same behavior, less
code.

* common/file_util: Make ReadFileToString and WriteStringToFile consistent

Makes the parameter ordering consistent, and also makes the filename
parameter a std::string. A std::string would be constructed anyways with
the previous code, as IOFile's only constructor with a filepath is one
taking a std::string.

We can also make WriteStringToFile's string parameter utilize a
std::string_view for the string, making use of our previous changes to
IOFile.

* common/file_util: Remove duplicated documentation comments

These are already present within the header, so they don't need to be
repeated in the cpp file.

* common/file_util: Make GetCurrentDir() return a std::optional

nullptr was being returned in the error case, which, at a glance may
seem perfectly OK... until you realize that std::string has the
invariant that it may not be constructed from a null pointer. This
means that if this error case was ever hit, then the application would
most likely crash from a thrown exception in std::string's constructor.

Instead, we can change the function to return an optional value,
indicating if a failure occurred.

* common/file_util: Remove unnecessary return at end of void StripTailDirSlashes()

While we're at it, also invert the conditional into a guard clause.

b3221c3180 file_util: Use an enum class for GetUserPath()
Instead of using an unsigned int as a parameter and expecting a user to
always pass in the correct values, we can just convert the enum into an
enum class and use that type as the parameter type instead, which makes
the interface more type safe.

We also get rid of the bookkeeping "NUM_" element in the enum by just
using an unordered map. This function is generally low-frequency in
terms of calls (and I'd hope so, considering otherwise would mean we're
slamming the disk with IO all the time) so I'd consider this acceptable
in this case.
