Increase the clearance between the USB-C diff pairs in order to minimize crosstalk

Re-route the differential tracks going from the USB-C switch IC to the EMI&TVS ICs along with some of the passives around the USB-C switch chip (similar placement to EmCraft's), add a 1uF cap to the EN pin of the 2.8V LDO in order to introduce a small (~10ms) delay between the 1.8V rail coming up and the 2.8V rail

Some component movments and routings around USB-C circuit.

Re-labelled signals around USB-C with naming scheme for differential routing (_P/_N names).
Routed some data lines behind USB connector.

Fix all DRC violations in the layout by making corrections to various footprints

Move USB_CN_D_P/_N vias closer together in order to maintain a more constant differential impedance

Route the USB-C differential signals going from the EMI&TVS ICs to the receptacle, add meander/serpentine bends to tracks which need differential pair skew/phase tuning

Rename all diff pairs such that they end in _P/_N rather than just P/N (underscore needed for diff pair routing)

Make the ETH PHY's crystal's load capacitors 27pF instead of 22pF, Cstray should now be 3.5pF instead of 7pF
