<pre style='padding-left: 1em; margin: 2em 0; border-left: 2px solid #ccc; line-height: 1.25; font-size: 105%; font-family: sans-serif'>Tests: Introduce assertion for comparing file paths independent of OS-specifics.
Introduces `WP_UnitTestCase_Base::assertSamePathIgnoringDirectorySeparators()` and an associated helper method `WP_UnitTestCase_Base::normalizeDirectorySeparatorsInPath()` to allow for comparing two file path strings independently of OS-specific differences.
The normalization is done in a separate method to also allow this method to be used for path normalization within test methods themselves, like for normalizing a group of paths in an array.
The pretty specific method name for the helper (`normalizeDirectorySeparatorsInPath()`) is an attempt to prevent naming conflicts with methods which may exist in plugin test suites build on top of the WP Core test suite.
Props jrf, hellofromTonya.
