test: migrate simulate/iter/bartlett-pulse to ULP-based assertions

[kgryte]

Resolves a part of #11352.

Description

What is the purpose of this pull request?

This pull request:

• migrates the tests for simulate/iter/bartlett-pulse from relative tolerance testing to ULP difference testing, following the idiom established in [RFC]: Migrate math/base/special packages from relative tolerance testing to ULP difference testing (tracking issue) #11352.
• replaces the delta/tol comparisons with t.strictEqual( isAlmostSameValue( actual.value, expected[ i ].value, 0 ), true, 'returns expected value' );, adds the @stdlib/assert/is-almost-same-value require, and removes the now unused @stdlib/constants/float64/eps require. The @stdlib/math/base/special/abs require is retained, as abs is still used by the bartlett test helper.

Notes on the ULP bound:

• Final ULP constant: 0 (used for all nine converted assertions).
• The bound was tightened by starting at 64 and lowering to the minimum integer which still passes over the full set of generated expected values; 0 is the measured minimum, i.e., the generated waveform values agree with the expected values bit-for-bit.
• The suite was run twice at the final bound to confirm determinism; both runs reported 3281/3281 passing.
• This matches the bound used for the sibling package in the same family, simulate/iter/bartlett-hann-pulse (test: migrate simulate/iter/bartlett-hann-pulse to ULP-based assertions #14614).

Only the test file is changed; no implementation or fixture changes.
