runtime: mark all Go symbols called from assembly in other packages This marks all Go symbols called from assembly in other packages with "go:linkname" directives to ensure they get ABI wrappers. Now that we have this go:linkname convention, this also removes the abi0Syms definition in the runtime, which was used to give morestackc an ABI0 wrapper. Instead, we now just mark morestackc with a go:linkname directive. This was tested with buildall.bash in the default configuration, with -race, and with -gcflags=all=-d=ssa/intrinsics/off. Since I couldn't test cgo on non-Linux configurations, I manually grepped for runtime symbols in runtime/cgo. Updates #31230.
