ADDED: PCB Tuning Profiles

Tuning profiles build on the previous delay tuning work to allow
the definition of track geometries per-layer for a given tuning
profile. These can be calculated from a target impedance (with
all relevant geometry taken from the board stackup), or entered
manually.

Tuning profiles can be configured to enable time-domain tuning,
and to automatically generate track geometry DRC rules for net
classes which have an assigned tuning profile.

Adds a DRC check for net classes with a tuning profile assigned
which is not itself defined.
