Format assignments more consistently (#10222 by @thorn0)

Previously, Prettier had a lot of trouble with figuring out how to break lines in assignments. E.g., long right-hand sides often stayed unbroken. Not anymore.

// Input
aParticularlyLongAndObnoxiousNameForIllustrativePurposes =
  anotherVeryLongNameForIllustrativePurposes;

aParticularlyLongAndObnoxiousNameForIllustrativePurposes =
  'a very long string for illustrative purposes'.length;

someReallyLongThingStoredInAMapWithAReallyBigName[pageletID] =
  _someVariableThatWeAreCheckingForFalsiness
    ? Date.now() - _someVariableThatWeAreCheckingForFalsiness
    : 0;

class x {
  private readonly rawConfigFromFile$: BehaviorSubject<any> = new BehaviorSubject(notRead);
}

// Prettier stable
aParticularlyLongAndObnoxiousNameForIllustrativePurposes = anotherVeryLongNameForIllustrativePurposes;

aParticularlyLongAndObnoxiousNameForIllustrativePurposes = "a very long string for illustrative purposes"
  .length;

someReallyLongThingStoredInAMapWithAReallyBigName[
  pageletID
] = _someVariableThatWeAreCheckingForFalsiness
  ? Date.now() - _someVariableThatWeAreCheckingForFalsiness
  : 0;

class x {
  private readonly rawConfigFromFile$: BehaviorSubject<any> = new BehaviorSubject(
    notRead
  );
}

// Prettier main
aParticularlyLongAndObnoxiousNameForIllustrativePurposes =
  anotherVeryLongNameForIllustrativePurposes;

aParticularlyLongAndObnoxiousNameForIllustrativePurposes =
  "a very long string for illustrative purposes".length;

someReallyLongThingStoredInAMapWithAReallyBigName[pageletID] =
  _someVariableThatWeAreCheckingForFalsiness
    ? Date.now() - _someVariableThatWeAreCheckingForFalsiness
    : 0;

class x {
  private readonly rawConfigFromFile$: BehaviorSubject<any> =
    new BehaviorSubject(notRead);
}
