libpayload: Add simple 32.32 fixed-point math API

struct fraction is slooooooooooow. This patch adds a simple 64-bit
(32-bits integral, 32-bits fractional) fixed-point math API that is
*much* faster when doing intensive graphics operations. It is optimized
for speed over accuracy so some operations may lose a bit more precision
than expected, but overall it's still plenty of bits for most use cases.

Also includes support for basic trigonometric functions with a small
lookup table.
