D3D: fix issues with multi-level 1x1 textures on D3D

Fixes NBA 2K11, maybe other things.
Remove Android <ucontext.h> hack.

There was a longstanding hack that defined ucontext_t manually to work
around the lack of this header on the Android NDK.  However, it looks
like newer NDK versions now have it like good little POSIX boys, and my
recent header reshuffle broke the build on those versions, presumably
because the real and fake definitions of ucontext_t end up included in
the same file where they weren't under the old organization.

Rather than try to revert the conflict, this commit just removes the
hack.  The buildbot's NDK will need to be upgraded.
Renamed EuRGB60 to PAL60
Added condition so that function to mix wiimote-speaker data into the master mixer is called only if wiimote is emulated.
rename CopyDataIntoBundle target name to avoid wx/qt conflict
Move library aggregation into common CMakeLists.txt; add missing libs to DolphinQt.

Fixes DolphinQt build (on OS X, anyway) when libav is enabled.
Vertex Loader: SSE implementations of more position/texcoord/normal formats

~35-45% faster NFS:HP2, possibly other vertex-bound games.
InputConfigFragment: Use a StringBuilder for string concatenation

This is the recommended way to join strings, since it doesn't destroy and recreate the string repeatedly.
