intel-gpu-overlay: Use RAPL PMU for power reading
Wire up to the RAPL PMU for GPU energy readings.
The only complication is that we have to add code to parse:
# cat /sys/devices/power/events/energy-gpu.scale
2.3283064365386962890625e-10
v2: Link with -lm.
v3: strtod can handle scientific notation, even though my initial
reading of the man page did not spot that. (Chris Wilson)
v4: Meson fix.
