RFR: 8270061: Change parameter order of ResourceHashtable [v3]

[Ioi Lam]

> The template parameter for ResourceHashtable is currently in this order:
> 
> template<
>     typename K, typename V,
>     unsigned (*HASH)  (K const&)           = primitive_hash<K>,
>     bool     (*EQUALS)(K const&, K const&) = primitive_equals<K>,
>     unsigned SIZE = 256,
>     ResourceObj::allocation_type ALLOC_TYPE = ResourceObj::RESOURCE_AREA,
>     MEMFLAGS MEM_TYPE = mtInternal
>     >
> class ResourceHashtable {...}
> 
> 
> However, more often than not, default values of `HASH` and `EQUALS` will be used, where the other parameters may need to be specified.
> 
> We should move the `HASH` and `EQUALS` parameters to the end of the parameter list.
