Implemented the Linux SocketCAN driver into CANBridge.

This is based off of the REVrobotics/CANBridge SocketCAN branch with lots of updates to compiling, driver code, and rewriting SocketCAN related code already existing to utilize the Linux kernel drivers.

Brings SocketCAN from upstream back to origin with already existing changes from main for workflows and other changes.
Some of the functions and implementations were not readily available nor created. This now resolves those issues.
This commit adds the implementation for the SocketCANDevice class, which was previously missing some functions and implementations. Now all required functions are available and the issues have been resolved.
This was missing the previous commit.

Change compiler options to have SocketCANThread actually compile instead of not.
Mirroring SerialDeviceThread.h as it was changed years ago.
Adding more compiler args to prevent other platforms that are not able to compile some platforms to compile files, as it would just error and fail the build.

Fixing broken functions such as `SocketCANDevice::GetID()` as it was not returning a string. This is now not implemented but it returns an `int` which is correct for the function.
Fix SocketCANDevice from being broken on compiles, from broken constructors to missing includes.
This is largely untested, however this should bring the functionality of the SocketCAN work somewhat back into play.
This tears out the majority of what was [candle_dll](https://github.com/HubertD/candle_dll/tree/master) for the Linux driver and implemented the Linux [SocketCAN](https://docs.kernel.org/networking/can.html) driver.

Preliminary testing shows that this does functionally work with a single SPARK MAX motor controller, however further testing may be required.

Plans to fully delete the serial driver are underway, as this is not supported or even functioning with current firmware.

SocketCAN devices aren't exclusively, changing it to something more generic.
