test: migrate math/base/special/asecf to ULP-based testing

[ujjwalv01]

Resolves a part of #11352.

Description

What is the purpose of this pull request?

This pull request:

• migrates the tests for math/base/special/asecf from computed relative tolerance (EPS-scaled delta <= tol) checks to ULP-based assertions;
• replaces the @stdlib/constants/float32/eps and @stdlib/math/base/special/abs requires with @stdlib/number/float32/base/assert/is-almost-same-value.
• both test/test.js and test/test.native.js are modified to use the new ULP assertions.

ULP bounds (one per fixture set, each tightened to the measured minimum):

fixture set	previous tolerance	ULP bound
medium_negative	2.0 * EPS	3
medium_positive	68.0 * EPS	97
large_positive	1.0 * EPS	1
large_negative	1.0 * EPS	1
larger_positive	1.0 * EPS	0
larger_negative	1.0 * EPS	1
huge_negative	1.0 * EPS	0
huge_positive	1.0 * EPS	0

Each bound is the smallest non-negative integer for which every fixture in the corresponding set passes. Starting from a high bound and lowering, the suite passes at the values above (4013/4013 assertions), and decrementing each of the five non-zero bounds by one produces exactly five failures - one per set ; confirming that no bound can be tightened further. The larger_positive, huge_negative, and huge_positive sets match the reference values exactly, hence a bound of 0.

The suite was run twice at the final bounds with identical results, so the bounds are not sensitive to FMA/contraction differences on this machine.
