Questa's FLI allows depositing over a forced signal

[ktbarrett]

In test_force_release.test_cocotb_writes_dont_overwrite_force_combo and test_force_release.test_cocotb_writes_dont_overwrite_force_registered, Questa's FLI seems to allow the user to overwrite the forced value using a regular deposit, causing the test to fail.
