Plane: remove FS parameters default values macros.

They just add an un-necessary level of indirection in the code. The parameters are run-time configurable now.

A short failsafe even can be triggered either by loss of RC control (see THR_FS_VALUE) or by loss of GCS control (see FS_GCS_ENABL). If in CIRCLE or RTL mode this parameter is ignored.
