WFLY-3292: adding base phase values for EE resource definition processors

Proposing a new way to handle DUP Phase values for DUPs that are strongly bound, such as extending abstract types to handle specific resources, in this case EE Resource Definitions:

- define in Phase.java base values and reserve a subset of values
- in WildFly main repo define a type where all DUP Phase values on the subset will be declared, using a base value + 0x0001, 0x0002, etc
