target/arm: Declare arm_log_exception() function publicly

In few commits we will split the M-profile functions from this
file, and this function will also be called in the new file.
Declare it in the "internals.h" header.
Since it is in the middle of a block of M profile functions,
move it previous to this block to ease the later refactor.
