Support for Translator and Macros

[MuhammadHammad001]

This pull request is linked to the feature enhancement PR#80 created in RISC-V ISAC related to Support for coverage of Privileged Architecture

In this pull request, I have added:

1. The Translator feature support that has been created in collaboration with @allenjbaum.
2. The Macros feature that can be used to improve the coverpoint writing process. Hence, the user may use the riscof command for the coverage to use his/her macros in the test label like:

    RVTEST_CASE(1,"//check ISA:=regex(.*32.*); check ISA:=regex(.*I.*Zicsr.*); def rvtest_mtrap_routine=True; def rvtest_strap_routine=True; def TEST_CASE_1=True; mac self",PMP_TOR_priority_r)

And add the header_file for the macros in the CLI for riscof as:

riscof coverage --config=config.ini --cgf-file=dataset.cgf --cgf-file=testing_coverpoint.cgf --suite=Testing_dir --env=env -h /home/header_file.yaml

Note: The documentation will be added within a day or two for the translator and the features as well for macros.
