 Rename _closure to _static_closure, apply naming consistently.

 Summary:
 In preparation for indirecting all references to closures,
 we rename _closure to _static_closure to ensure any old code
 will get an undefined symbol error.  In order to reference
 a closure foobar_closure (which is now undefined), you should instead
 use STATIC_CLOSURE(foobar).  For convenience, a number of these
 old identifiers are macro'd.

 Across C-- and C (Windows and otherwise), there were differing
 conventions on whether or not foobar_closure or &foobar_closure
 was the address of the closure.  Now, all foobar_closure references
 are addresses, and no & is necessary.

 CHARLIKE/INTLIKE were not changed, simply alpha-renamed.

 Part of remove HEAP_ALLOCED patch set (#8199)

 Depends on D265
