* FuriHal: properly handle high priority USB IRQ, change CDC decriptor to use separate TX/RX endpoints * Furi: drop task handle, cleanup casts and memory corrupt in threads * FuriHal: update max power in USB descriptors * Furi: properly handle thread free if thread was not started * Furi crash: meaningful interrupt name instead of id --------- Co-authored-by: SG <who.just.the.doctor@gmail.com>
