perf(napi): optimize primitive napi functions (#16163)
This optimization applies on `napi_get_undefined`, `napi_get_null` &
`napi_get_boolean`.

```
# main

benchmark               time (avg)             (min … max)       p75       p99      p995
---------------------------------------------------------- -----------------------------
warmup              482.55 ps/iter   (462.5 ps … 15.67 ns)    475 ps    525 ps  829.1 ps
napi_get_undefined   25.07 ns/iter   (24.03 ns … 36.87 ns)  25.37 ns  27.09 ns  34.85 ns
```
