true-fantom/math: Add true sin/cos/tan block. (TurboWarp#1959)

sorry mio

In Scratch/Turbowarp, the sin/cos/tan/asin/acos/atan blocks don't return
as expected-- they're run through several other equations to deal with
rounding, and to make the blocks compatible with degrees.

While this makes the blocks more user-friendly, it can be annoying for
people who want the original functions to have to essentially undo the
extra calculations. This PR adds a new block to the Math extension which
introduces a new block, featuring all the same trig functions, but
returning exactly what their Javascript Math counterpart does.
