test: migrate blas/ext/base/drrss to ULP-based assertions

[DivyanshuVortex]

Resolves a part of #11352.

Description

What is the purpose of this pull request?

This pull request:

• migrates the tests for blas/ext/base/drrss from relative tolerance testing to ULP difference testing, per [RFC]: Migrate math/base/special packages from relative tolerance testing to ULP difference testing (tracking issue) #11352.
• replaces the legacy actual[ i ] === expected[ i ] / delta <= tol branch in isApprox across the test files with t.strictEqual( isAlmostSameValue( actual[ i ], expected[ i ], ulp ), true, 'returns expected value' );.
• adds the @stdlib/assert/is-almost-same-value require and drops unused abs and EPS requires.

These bounds were determined empirically using a script that calculated the maximum ULP difference across all test combinations.

I believe these tests are broken. The third argument should be an array. Here, we are passing a number literal. This should be fixed here and in the other test files. It looks like we shouldn't need isApprox at all, as z is a scalar.

We should also check whether other *rrss packages have similar mistakes.
