Fix two minor understandability issues in common

Pica/VertexShader: Fix a bug caused due to incorrect assumptions of consecutive output register tables.

Add static_cast around expressions where the compiler doesn’t deduce the right type

arm_interface: Get rid of GetTicks.

Removes a TODO.

GPU: Implemented the flip_data (bit 0) bit in display transfers.

EmuWindow: Fixed a reference to a temporary variable

 in GetTouchState()

Pica/VertexShader: Fix a bug caused due to incorrect assumptions of consecutive output register tables.

We now write create a temporary buffer for output registers and copy all of them to the actual output vertex structure after the shader has run. This is technically not necessary, but it's easier to vectorize in the future.

Touchpad support

Implement SetLcdForceBlack and add implementation for color filling in the GPU code

dyncom: Minor cleanup

Assemblers will exit with an error when trying to assemble instructions with disallowed registers.

GPU: Implemented more depth buffer formats.

This fixes the horizontal lines in Picross E, Cubic Ninja, Cave Story 3D and possibly others

Pica/PrimitiveAssembly: Fix triangle strips and fans being generated with incorrect winding order.

GPU: Use the correct position for the finished bit in memory fills

GPU: Corrected the 24 bit memory fills component order
