[Node.js] Tests for cos, sin, tan can't meet the tolerance requirement

[mingmingtasd]

Based on dml backend, running npm run test-ops through node.js under webnn-native/node will get results as below:

test element-wise unary operations
    √ abs
    √ ceil
a(-0.3924400508403778) b(-0.39242464) delta(0.00001541084037781637)
    59) cos
    √ exp
    √ floor
    √ log
    √ neg
a(0.9874919056892395) b(0.98748258) delta(0.000009325689239503276)
    60) sin
a(6.260713577270508) b(6.26066374) delta(0.00004983727050777986)
    61) tan

The result can't meet the criterion in webnn-polyfill tests:

export const opFp32AccuracyCriteria =
    new AccuracyCriterion(1e-6, 5.0 * 1.1920928955078125e-7);

In webnn-native end2end tests, criterion (fabs(output - expected) < 0.005f) can let tests pass.
