This change adds per-section tracepoints to the Pixel 6 (and beyond)
implementation of dumpstateBoard for the purpose of debugging
possibly-long sections.
This change is analagous to the previous gs101/gs201 tracepoint
additions at ag/20414147 and ag/20413969.
Test: Build+flash; verify that a trace of a bug report contains
dumpstate board sections.
