user32: Make more functions hot-patchable for Steam

[Krzysztof Nowicki]

Steam is known to hot-patch some Win32 API entrypoints. A number of them
have already been declared as hot-patchable using the ms_hook_prologue
attribute.

When trying to run Mount & Blade Warband I encountered more functions
that were hot-patched. Patching user32.GetSysColor was enough to get the
game working, however there was more.

The patch below is a result of a binary comparison between the original
user32.dll code and a memory dump done after the M&B executable started.
The comparison showed a number of functions that have been patched, but
were not declared as hot-patchable.

I hope to also review other DLLs in the same way.
