Have floating point register values in native crash events

[Angelodaniel]

Is there a way to get floating point register values in native crash events? I don't think it's possible as of today OOTB but as we have gaming companies we help I think could make sense: This extra information can be crucial for diagnosing crashes in math-heavy code, games, audio processing, image processing, machine learning, or any code using SIMD optimizations.

NATIVE-148

(Informational) This would not only need work on the SDK side, but also in Relay since we currently expect Registers to be 64-bit values, whilst FP registers can be up to 128 bits large.

(WIP) Relevant code on how/where we collect register data:

• inproc
• breakpad and minidump generator
• crashpad (todo: figure out why it seems like we don't actually have this in the .dmp files on Sentry)
