Cody Tapscott 70dc910086 std.math: Add O(log N) implementation of log2(x) for comptime_int ...

Since Zig provides @clz and not @ffs (find-first-set), log2 for comptime
integers needs to be computed algorithmically. To avoid hitting the
backward branch quota, this updates log2(x) to use a simple O(log N)
algorithm.
