6467b01de2 partition_data_manager: Reserve and insert data within output vector in DecryptPackage2()
We can just reserve the memory then perform successive insertions
instead of needing to use memcpy. This also avoids the need to zero out
the output vector's memory before performing the insertions.

We can also std::move the output std::vector into the destination so
that we don't need to make a completely new copy of the vector, getting
rid of an unnecessary allocation.

Additionally, we can use iterators to determine the beginning and end
ranges of the std::vector instances that comprise the output vector, as
the end of one range just becomes the beginning for the next successive
range, and since std::vector's iterator constructor copies data within
the range [begin, end), this is more straightforward and gets rid of the
need to have an offset variable that keeps getting incremented to
determine where to do the next std::memcpy.

781fd7983c partition_data_manager: Remove unused std::map instance within DecryptPackage2()
Aside from emplacing elements into the map, the map itself is never
actually queried for contained data.

e0c76226ad partition_data_manager: Take package2_keys by const reference
These are only ever read from, so we don't need to make a copy of all
the keys here.

3d9df49619 partition_data_manager: Move IV data to where it's needed in DecryptPackage2()
Given it's only used in one spot and has a fairly generic name, we can
just specify it directly in the function call. This also the benefit of
automatically moving it.

bc2196bb09 partition_data_manager: Remove commented out code
Commented out code shouldn't be left in without a reason indicating why
in a comment.

f56a8da46a partition_data_manager: Dehardcode array bounds
Instead, we can make it part of the type and make named variables for
them, so they only require one definition (and if they ever change for
whatever reason, they only need to be changed in one spot).

d257a3b56c partition_data_manager: Take VirtualFile by const reference in constructor
Given the VirtualFile instance isn't stored into the class as a data
member, or written to, this can just be turned into a const reference,
as the constructor doesn't need to make a copy of it.

e96d69c328 partition_data_manager: Amend constructor initializer list order
Orders the members in the exact order they would be initialized. This
also prevents compiler warnings about this sort of thing.

Gets unused includes out of the headers and moves them into the cpp file
if they're used there instead.
