gpu: nvgpu: Add NVGPU_IOCTL_CHANNEL_SET_BOOSTED_CTX

This ioctl can be used on gp10b to set a flag in the context header
indicating this context should be run at elevated clock
frequency. FECS ctxsw ucode will read this flag as part of the context
switch and will request higher GPU clock frequencies from BPMP for the
duration of the context execution.
