tools/power x86_energy_perf_policy: Add Android MSR device support

Browse source

Add support for Android MSR device paths which use /dev/msrN format
instead of the standard Linux /dev/cpu/N/msr format. The tool now
probes both path formats at startup and uses the appropriate one.

This enables x86_energy_perf_policy to work on Android systems where
MSR devices follow a different naming convention while maintaining
full compatibility with standard Linux systems.
