unicode/norm: lazy load recompMap from string

recompMap gets populated on init, which requires 21kB of memory.
Instead populate it only when we need it.

This will put it in the rodata section of the binary, which means that
the Go compiler can apply better optimizations to it. The string is an
alternating series of 4 byte keys and 4 byte values, which get built
into a map the first time they are required.

Updates golang/go#26752.
