Update the default balance_performance EPP to 64. This gives better
performance and also perf/watt compared to current value of 115.

For example:

Speedometer 2.1
score: +19%
Perf/watt: +5.25%

Webxprt 4 score
score: +12%
Perf/watt: +6.12%

3DMark Wildlife extreme unlimited score
score: +3.2%
Perf/watt: +11.5%

Geekbench6 MT
score: +2.14%
Perf/watt: +0.32%

Also update balance_power EPP default to 179. With this change:
Video Playback power is reduced by 52%
Team video conference power is reduced by 35%

With Power profile daemon now sets balance_power EPP on DC instead of
balance_performance, updating balance_power EPP will help to extend
battery life.
