6e1c6297a3 fixed_point: Mark default constructor as constexpr
Ensures that a fixed-point value is always initialized

This likely also fixes several cases of uninitialized values being
operated on, since we have multiple areas in the codebase where the
default constructor is being used like:

Common::FixedPoint<50, 14> current_sample{};

and is then followed up with an arithmetic operation like += or
something else, which operates directly on FixedPoint's internal data
member, which would previously be uninitialized.

b6119a55f9 fixed_point: Mark copy/move assignment operators and constructors as constexpr
Given these are just moving a raw value around, these can sensibly be
made constexpr to make the interface more useful.

0cfd90004b fixed_point: Mark std::swap and move constructor as noexcept
These shouldn't throw and can influence how some standard algorithms
will work.

2cc9d94060 fixed_point: Mark relevant member function [[nodiscard]]
Marks member functions as discard, where ignoring the return value would
be indicative of a bug or dead code.

0101ef9fb1 fixed_point: Make to_uint() non-const
This calls round_up(), which is a non-const member function, so if a
fixed-point instantiation ever calls to_uint(), it'll result in a
compiler error.

This allows the member function to work.

While we're at it, we can actually mark to_long_floor() as const, since
it's not modifying any member state.

5000d814af fixed_point: Use variable templates and concepts where applicable
Makes a few things a little less noisy and removes the need for SFINAE
in quite a few functions.

88ccdaf10a fixed_point: Replace CONSTEXPR14 with constexpr
As we require the latest C++ standards to compile yuzu, checking for C++14 constexpr is not needed.

chore: make yuzu REUSE compliant
[REUSE] is a specification that aims at making file copyright
information consistent, so that it can be both human and machine
readable. It basically requires that all files have a header containing
copyright and licensing information. When this isn't possible, like
when dealing with binary assets, generated files or embedded third-party
dependencies, it is permitted to insert copyright information in the
`.reuse/dep5` file.

Oh, and it also requires that all the licenses used in the project are
present in the `LICENSES` folder, that's why the diff is so huge.
This can be done automatically with `reuse download --all`.

The `reuse` tool also contains a handy subcommand that analyzes the
project and tells whether or not the project is (still) compliant,
`reuse lint`.

Following REUSE has a few advantages over the current approach:

- Copyright information is easy to access for users / downstream
- Files like `dist/license.md` do not need to exist anymore, as
  `.reuse/dep5` is used instead
- `reuse lint` makes it easy to ensure that copyright information of
  files like binary assets / images is always accurate and up to date

To add copyright information of files that didn't have it I looked up
who committed what and when, for each file. As yuzu contributors do not
have to sign a CLA or similar I couldn't assume that copyright ownership
was of the "yuzu Emulator Project", so I used the name and/or email of
the commit author instead.
