fix: improve binary expression assignment breaking

[jtkiesel]

What changed with this PR:

Assignments with binary expressions (including those within the expression of a ternary) are now broken more similarly to the way Prettier does with JavaScript/TypeScript.

Example

Input

Aaaaaaaaaa aaaaaaaaaa = bbbbbbbbbb(cccccccccc, dddddddddd, eeeeeeeeee) != ffffffffff ? gggggggggg : hhhhhhhhhh;

Aaaaaaaaaa aaaaaaaaaa = bbbbbbbbbb(cccccccccccccccccccc, dddddddddddddddddddd, eeeeeeeeee) != ffffffffff ? gggggggggg : hhhhhhhhhh;

Aaaaaaaaaa aaaaaaaaaa = bbbbbbbbbb(cccccccccccccccccccc, dddddddddddddddddddd, eeeeeeeeeeeeeeeeeeee) != ffffffffff ? gggggggggg : hhhhhhhhhh;

var aaaaaaaaaa = bbbbbbbbbbbb || cccccccccc ? dddddddddd + eeeeeeeeee : ffffffffff + gggggggggg;

Output

Aaaaaaaaaa aaaaaaaaaa =
  bbbbbbbbbb(cccccccccc, dddddddddd, eeeeeeeeee) != ffffffffff
    ? gggggggggg
    : hhhhhhhhhh;

Aaaaaaaaaa aaaaaaaaaa =
  bbbbbbbbbb(cccccccccccccccccccc, dddddddddddddddddddd, eeeeeeeeee) !=
  ffffffffff
    ? gggggggggg
    : hhhhhhhhhh;

Aaaaaaaaaa aaaaaaaaaa =
  bbbbbbbbbb(
    cccccccccccccccccccc,
    dddddddddddddddddddd,
    eeeeeeeeeeeeeeeeeeee
  ) !=
  ffffffffff
    ? gggggggggg
    : hhhhhhhhhh;

var aaaaaaaaaa =
  bbbbbbbbbbbb || cccccccccc
    ? dddddddddd + eeeeeeeeee
    : ffffffffff + gggggggggg;

Output
