Lars-Peter Clausen 5f479cbad4 Store lexical positions in LineInfo
Several source and netlist objects inherit `LineInfo` while separately
storing the lexical position associated with the same source location. This
requires callers to copy the file, line, and lexical position independently.

Add the lexical position to `LineInfo`. Have `set_line()` initialize it when
it is unset, so new objects inherit the complete source location while later
diagnostic location updates preserve their established declaration order.
Initialize the field to `UINT_MAX` so zero remains available as a valid
scanner position and missing initialization is distinguishable. Have
`FILE_NAME()` preserve a more precise identifier position.

Remove constructor parameters that duplicate the position supplied through
`FILE_NAME()`. Use the shared field for identifiers, wires, events, event
triggers, nets, and elaborated events. Assign static class property nets
their declaration location since they previously relied on the standalone
`NetNet` position defaulting to zero.
