Many of our enumerations follow a standard scheme where the values can be treated as signed however there are some where the value must be treated as signed and others that are simple enumerations where there is no clear ordering to the values. Provide new field types SignedEnum and UnsignedEnum which allows the signedness to be specified in the sysreg definition and emit a REG_FIELD_SIGNED define for these which is a boolean corresponding to our current FTR_UNSIGNED and FTR_SIGNED macros. Existing Enums will need to be converted, since these do not have a define generated anyone wishing to use the sign of one of these will need to explicitly annotate that field so nothing should start going wrong by default.
