encoding/asn1: remove allocation from init
asn1 allocates due to reflect.TypeOf(new(big.Int)) in init time.
We could replace it with (*big.Int)(nil).
Before:
init encoding/asn1 @1.0 ms, 0.009 ms clock, 224 bytes, 7 allocs
After:
init encoding/asn1 @0.70 ms, 0.002 ms clock, 192 bytes, 6 allocs
Fixes #55973
