20a3661d6c Clarify which architectures do/don't need sa_restorer. 
In particular: 32-bit x86 doesn't need sa_restorer either.

I still don't fully understand why arm32 and x86-64 do, so I've left the
comments in those .S files alone. I haven't (knowingly) tested
compiler-rt since we switched from libgcc (which is what the comments
refer to), but I have tested libunwindstack since we switched from
libunwind, and that does fail existing bionic tests for unwinds through
signal frames --- I just don't know why, or whether there's a better fix.

Anyway, local testing suggests that the 32-bit x86 code is vestigial, so
let's get rid of it.

Kernel headers coming from:

Git: https://android.googlesource.com/kernel/common/
Branch: android-mainline
Tag: android-mainline-6.7

NOTE: The file bionic/libc/kernel/uapi/linux/usb/f_accessory.h was
deleted in the 6.7 kernel along with the functionality. However,
there is no current replacement. For now keep the file here, but at
some point when the new implementation is ready, this file will need to
be moved to the places that still need to be backwards compatible.

Test: Builds and bionic unit tests pass on raven.
Test: Able to log in to an Android GO 32 bit device.
