Lioncash e77337588e 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.

Lioncash 11e9bee91d 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.

Lioncash 2b1fcc8a14 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.

Lioncash e3b2539986 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.

Lioncash 8cd3d9be26 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.

Weiyi Wang bfe84f06f2 string_util: remove TString conversion for windows
First of all they are foundamentally broken. As our convention is that std::string is always UTF-8, these functions assume that the multi-byte character version of TString (std::string) from windows is also in UTF-8, which is almost always wrong. We are not going to build multi-byte character build, and even if we do, this dirty work should be handled by frontend framework early.

Lioncash 0ba7fe4ab1 file_util: Use a u64 to represent number of entries
This avoids a truncating cast on size. I doubt we'd ever traverse a
directory this large, however we also shouldn't truncate sizes away.

Lioncash d66b43dadf 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.

file_util: Make move constructor/assignment operator and related functions noexcept
Without this, it's possible to get compilation failures in the (rare) scenario where
a container is used to store a bunch of live IOFile instances, as they may be using
std::move_if_noexcept under the hood. Given these definitely don't throw exceptions
this is also not incorrect to add either.

file_util: Add static assertions to ReadBytes() and WriteBytes()
Ensure that the actual types being passed in are trivially copyable. The internal
call to ReadArray() and WriteArray() will always succeed, since they're passed a pointer to char*
which is always trivially copyable.

file_util: Remove compiler version checks around is_trivially_copyable()
The minimum clang/GCC versions we support already support this. We can also
remove is_standard_layout(), as fread and fwrite only require the type to be
trivially copyable.

Fixes #1115.

Also improves the performances of DiskArchive’s directory
implementation a lot, simply by not going through the entire tree
instead of just listing the first level files.

Thanks to JayRoxFox for rebasing this on current master!

archshift b3cfcf55ea Refactor ScanDirectoryTreeAndCallback to separate errors and retvals
ScanDirectoryTreeAndCallback, before this change, coupled error/return
codes and actual return values (number of entries found). This caused
confusion and difficulty interpreting the precise way the function
worked.

Supersedes, and closes #1255.
