QEMU sensor support

qemu/hw/sensor is a folder containing various emulated sensors, which appear to be written by giants such as Nokia, IBM, Qualicom, Bytedance, and Google with only one of them being written by a small company. There are a few kinds of sensors. Some may be able to passthrough, and others can only be spoofed/faked via GUI.

1. Analog Devices ADM1272 High Voltage Positive Hot Swap Controller and Digital Power Monitor with PMBus (by Google) - type: Hot Bus (don't understand what it is)
2. Infineon DPS310 temperature and humidity sensor (IBM) - Type: temperature sensor and humidity sensor combo. To my knowledge, no Apple device comes with a humidity sensor, but the temperature sensor should be able to be able to passthrough either CPU temperature of the M1 (due to the lack of environmental thermal sensors on all Apple devices excluding the Apple Watch) and temperature sensors should be selected by the user
3. SMSC EMC141X temperature sensor (Bytedance) - Type: temperature sensor
4. PMBus device for Renesas Digital Multiphase Voltage Regulators (Google) - Type: voltage monitor (I don't understand what this device does either)
5. LSM303DLHC I2C magnetometer. (Linaro Ltd.) - Type: magnetometer. Magnetometers should be available to be passed through on iPhone when selected but like the humidity sensor on macOS can only be spoofed on Mac.
6. Maxim MAX31785 PMBus 6-Channel Fan Controller (Qualcomm) - Type: Fan controller. Fan control could be passed through on macOS devices.
7. Maxim MAX34451 PMBus 16-Channel V/I monitor and 12-Channel Sequencer/Marginer (Google) - Type: power supply monitor (don't understand what they do either)
8. Texas Instruments TMP105 temperature sensor (Nokia) - Type: Temperature sensor
9. Texas Instruments TMP421 temperature sensor (IBM) - Type: Temperature sensor
