gpu: nvgpu: Split ctxsw_trace API into non-Linux component

Split the ctxsw trace "core" API code into <nvgpu/ctxsw_trace.h>. This
is not perect though since there's some Linuxisms present in the HAL
and as such that code has to be hidden by the ctxsw tracing CONFIG. But
this patch should work for QNX such that it will allow the code to
build as long as CONFIG_GK20A_CTXSW_TRACE is not set.

Also fix the copywrite notice in the ctxsw code present under
common/linux to be GPL.
