Silent Fan profile added (v3.0)

[Adravil]

Option Silent4000RPMThreshold in FanControl.dll.ini now defines at what temperature Silent fan curve should reach 4000 RPM. Minimum -- 80, default -- 85, maximum -- 90.

More tests are welcomed of course, but according to my tests:

• in Baldur's Gate 3 with any heavy graphical settings
• with Silent4000RPMThreshold being set to default value (85)
• with Silent fan profile-curve activated
• and TDP set to 15W

SoC's temperature stays at ~90°C, what pushes the fan up to 6450 RPM and leaves some headroom for sudden jumps (to ~95°C, never seen 100°C). In this scenarion noise level is high, but that's expected because of the 15W TDP level.

• If you think that's still too risky, we can drop the default Silent4000RPMThreshold value to 80.
• With Silent4000RPMThreshold kept at 85, the TDP limitation to 12W lowers temperatures by 5°C (average under stress from ~90°C to ~85°C, sudden jumps from ~95°C to ~90°C). Such change eliminates most of the noise heard in previous scenario (Silent4000RPMThreshold == 85, TDP == 15W).
• Lowering the TDP level to 10W eliminates the noise almost completely.

@Adravil Thank you. I merged this in here with small amendments: 0518e30
