Update SoundTouch to 2.3.2 commit 1eda9c0b01039f29d230a46cda9f2290bbd1f62b

This update includes every Dolphin-specific modification I could find in the commit history. Hopefully no issues arise from this update. This PR superscedes #10671. I'm making it because I upstreamed some warning fixes to SoundTouch itself. According to #10671, this also patches some CVEs, which is a plus.

Can you split out the Dolphin-specific modifications into an extra commit?

(That is, make this two commits: One commit to update to the unmodified 2.3.2, then one commit to apply the Dolphin-specific modifications on top.)

[Minty-Meeo]

Certainly, that would make it clearer.

Problematic typedefs were moved into the soundtouch namespace with 16c9032.
SAMPLETYPE was changed from floats to shorts, and x86 optimizations were disabled with 8ff26a6.
Nonexact SIMD optimizations were enabled with d8f5ecf.
The "soundtouch_config.h" include started being commented out with 91fe5cc.
Exception handling I think has always been disabled.
If I recall, I put the change in BPMDetect.cpp to remove the non-standard _USE_MATH_DEFINES define.

I want to mention that most of these seem to be more easily configurable using either the soundtouch_configure.h header or defining things from the command line. I am bad at CMake, though, so I couldn't figure out the latter and left it as it was.

Looks good to me. Tested on Windows.
