[NTUser] Fix Strings and Format to Hooks

[NTUser] Fix Strings and Format to Hooks

Allocate heap instead of data segment to be used for callbacks on user side.
Move and correct initial hook call out setup. Use it in more than one hook call.

This fixes issues with strings out of alignment and use of kernel pointers.

See CORE-13907 and CORE-16769. KsStudio still needs retested.

Small wow update.
