stream: improve write performance

[ronag]

This is inspired by #30710.

Depends on #30733 (which is included).

Improves performance of write by avoiding process.nextTick and a number of conditions when possible in the hot path in sync mode.

``` confidence improvement accuracy (*) (**) (***) streams/writable-manywrites.js n=2000000 *** 1085.31 % ±19.19% ±25.86% ±34.31% ````

EDIT: A bit more modest improvement after #30710

                                                      confidence improvement accuracy (*)   (**)  (***)
 streams/writable-manywrites.js sync='no' n=2000000                  0.10 %       ±1.46% ±1.94% ±2.54%
 streams/writable-manywrites.js sync='yes' n=2000000        ***      8.43 %       ±1.73% ±2.30% ±3.00%

Note since #30733 is probably semver major, this should be the same.

Added semver-major label due to e828f510.

Let's park this until #30733 is landed
