Add SvIsBOOL() macro to test for SVs being boolean-intent
These are identified as being static shared COW strings whose string
buffer points directly at PL_Yes / PL_No
Define sv_setbool() and sv_setbool_mg() macros
Use sv_setbool() where appropriate
Have sv_dump() annotate when an SV's PV buffer is one of the PL_(Yes|No) special booleans
