Subject: [PATCH] test: migrate `constants/float64/half-ln-two` to ULP-based
 assertions

Replace the relative tolerance assertion in the `export equals
0.5*ln(2)` test case with an ULP difference assertion using
`@stdlib/assert/is-almost-same-value`. The `delta`/`tol`
computations and the now-unused `@stdlib/math/base/special/abs`
and `@stdlib/constants/float64/eps` imports are removed.

`0.5 * ln( 2.0 )` is bit-identical to the exported constant, so
the measured ULP difference is 0, which is also the tightest
possible bound.
