tcg/arm: Simplify usage of encode_imm

We have already computed the rotated value of the imm8
portion of the complete imm12 encoding.  No sense leaving
the combination of rot + rotation to the caller.

Create an encode_imm12_nofail helper that performs an assert.

This removes the final use of the local "rotl" function,
which duplicated our generic "rol32" function.
