Split AccessorDecl out from FuncDecl. NFC.

Browse Source 
This has three principal advantages:

- It gives some additional type-safety when working
  with known accessors.

- It makes it significantly easier to test whether a declaration
  is an accessor and encourages the use of a common idiom.

- It saves a small amount of memory in both FuncDecl and its
  serialized form.
