…I_WORKING_SET_EX_INFORMATION, adjust function names

The definition of PSAPI_WORKING_SET_EX_BLOCK was not correct. The outer
definition is a UNION with two members:

- ULONG_PTR Flags and
- another anonymous union holding two bitfield definitions

It effectively defines a union with 3 defintions.

The bitfield definition differs between 32bit and 64bit. The 32bit
version defines data elements filling exactly the 32bits a single
ULONG_PTR can hold. The 64bit version adds an additional 32bit reserved
element, which agains fill the full size a single ULONG_PTR can hold on
64bit.

The two bitfield definitions both map to ULONG_PTR, so 
PSAPI_WORKING_SET_EX_BLOCK is basicly just a ULONG_PTR with C syntactic
sugar for decoding.

The PSAPI_WORKING_SET_EX_BLOCK is only used in 
PSAPI_WORKING_SET_EX_INFORMATION and given that the union definition
of PSAPI_WORKING_SET_EX_BLOCK is syntactic sugar, we can drop the
definition and integrate the decoding logic directly into
PSAPI_WORKING_SET_EX_INFORMATION.
