[roll] Roll third_party/fuchsia-infra-bazel-rules [roll] Roll third_party/googletest Add a `DistanceFrom()` matcher for general distance comparison.

We have a bunch of matchers for asserting that a value is near the target value, e.g.
`DoubleNear()` and `FloatNear()`. These matchers only work for specific types (`double` and `float`). They are not flexible enough to support other types that have the notion of a "distance" (e.g. N-dimensional points and vectors, which are commonly used in ML).

In this diff, we generalize the idea to a `DistanceFrom(target, get_distance, m)` matcher that works on arbitrary types that have the "distance" concept (the `get_distance` argument is optional and can be omitted for types that support `-`, and `std::abs()`). What it does:

1. compute the distance between the value and the target using `get_distance(value, target)`; if `get_distance` is omitted, compute the distance as `std::abs(value - target)`.
2. match the distance against matcher `m`; if the match succeeds, the `DistanceFrom()` match succeeds.

Examples:

```
  // 0.5's distance from 0.6 should be <= 0.2.
  EXPECT_THAT(0.5, DistanceFrom(0.6, Le(0.2)));

  Vector2D v1(3.0, 4.0), v2(3.2, 6.0);
  // v1's distance from v2, as computed by EuclideanDistance(v1, v2),
  // should be >= 1.0.
  EXPECT_THAT(v1, DistanceFrom(v2, EuclideanDistance, Ge(1.0)));
```
