version: Use the find_resource function instead of the 16-bit entry points to load 16-bit resources.

The test was adopted from the ddraw test, where GetPrivateData does not
addref. The test code was adjusted, the comment apparently not.

We only need to handle the case where "value" is TRUE, since the stateblock
data will be filled with zeroes by default.

This is redundant because we call stateblock_savedstates_set() further down.

comctl32/datetime: Always store a recalculated day of week instead of a value passed in (DTM_SETSYSTEMTIME).
