[TASK] Isolate functional test fixture assets for EXT:frontend

This patch removes fixture cross-dependencies from EXT:frontend to
EXT:core. The existing "pages_frontend.csv" file is identical to
the Core's "pages.csv" Fixture and can be switched. A very simple
Fluid Partial (one liner) is copied to be distinct to EXT:frontend.

Assets are copied to be unique and prevent side-effects when
files are changed at their original location. Tests should be
side-effect free and isolated.

Remaining exemption for cross-dependencies are references to:

EXT:core/Tests/Functional/Fixtures/Frontend/JsonRenderer.typoscript
EXT:core/Tests/Functional/Fixtures/Extensions/test_irre_csv
EXT:core/Tests/Functional/Fixtures/Extensions/test_eid
EXT:core/Tests/Functional/Fixtures/Extensions/test_classic_content
EXT:core/Tests/Functional/Fixtures/Extensions/test_irre_mm
EXT:core/Tests/Functional/Fixtures/Extensions/test_irre_mnsymmetric
EXT:core/Tests/Functional/Fixtures/Extensions/test_irre_foreignfield
EXT:core/Tests/Functional/Fixtures/Extensions/test_irre_mnattributeinline
EXT:core/Tests/Functional/Fixtures/Extensions/test_irre_mnattributesimple

These central fixtures should not be redundantly stored,
and are fittingly placed in the "EXT:core" space.
