AK+Everywhere: Add sincos and use it in some places

Calculating sin and cos at once is quite a bit cheaper than calculating
them individually.
x87 has even a dedicated instruction for it: `fsincos`.

LibDSP: Generalize & improve FFT

Several related improvements to our Fast Fourier Transform
implementation:
- FFT now operates on spans, allowing it to use many more container
  types other than Vector. It's intended anyways that FFT transmutes the
  input data.
- FFT is now constexpr, moving the implementation to the header and
  removing the cpp file. This means that if we have static collections
  of samples, we can transform them at compile time.
- sample_data.data() weirdness is now gone.

SoundPlayer+LibDSP: Move the FFT implementation to LibDSP

LibDSP can greatly benefit from this nice FFT implementation, so let's
move it into the fitting library :^)

Note that this now requires linking SoundPlayer against LibDSP. That's
not an issue (LibDSP is rather small currently anyways), as we can
probably make great use of it in the future anyways.
