Toolchain fixes (#3451)

toolchain: updated to v33 with debugging & other fixes
toolchain: better error handling during update/env configuration process
debugging: improved udev rules file, added readme on installation
firmware: bumped compiler C/C++ standards (stricter code checks)
firmware: fixed warnings emerging from newer standards
ufbt: FBT_NOENV is now also supported by ufbt
fbt: added ccache-related variables to env forward list on Windows

+## Installing udev rules
+
+On Linux, unprivileged users need to be in the `dialout` group to access serial ports and other USB devices. 
+
+To add your user to the `dialout` group, run the following command:
+
+```bash
+sudo usermod -a -G dialout $USER
+```
+
+To install the udev rules needed for debugging & CLI access to Flipper, run the following command:
+
+```bash
+sudo cp 41-flipper.rules /etc/udev/rules.d/
+sudo udevadm control --reload-rules
+sudo udevadm trigger
+```
+
+Note that not all possible debug interfaces are listed the `41-flipper.rules` file. If your interface is not supported out of the box, you may need to add a a rule for it. You can do so by adding a new line to the file according to udev rules syntax. Use `lsusb -v` to find the vendor and product IDs of your device.
