faft-gsc: use gsc_ecrst_pulse to reset the EC

Use `ecrst pulse` to reset the EC and enter dev mode.

Update faft-gsc tests to use gsc_ecrst_pulse for cold reset. `ecrst
pulse` can reset the EC and keep the EC-EFS2 boot mode in sync with the
system state when ccd is locked.

This changes try to use the ecrst pulse control if it's available. If it
isn't, it falls back to uring the old controls. A follow up CL will
remove the backup methods after the labstation image has ecrst pulse
support in hdctools.

TEST=run firmware_Cr50DevMode and firmware_Cr50Testlab on hatch
