Subject: [PATCH] test: migrate math/base/special/binomcoeff native tests to
 ULP-based assertions

Replaces the manual delta/tolerance comparison in test.native.js with
isAlmostSameValue, mirroring the pattern already used in test.js for this
package. The tightest ULP bound found is 2 (matches the JS binding's
bound).

Ref: #11352
