feat(LibraryFiltersComponent): add research project filtering functionality

[hirokiterashima]

Changes

• This change set allows authors to specify ResearchProject (RP) tags ("NLP-TIPS", "ARISE", etc) to library units. This is represented in the project JSON in metadata.researchProjects array. This will allow teachers and grant reviewers to quickly search for units that were created for certain research projects.
• Add select menu that appears only when there are library units with RP tags
• Update the filtered units according to the users' selections of the new RP tags

Setup

• To add RP tag to a unit, open the unit's JSON editing view in the AT and add the following field to the metadata block:

        "researchProjects": [
            "ARISE",
            "NLP-TIPS"
        ],

Test

• Test with feat(ProjectMetadata): Add Research Projects field WISE-API#284
• When no units with RP tags exists
• When one or more units with RP tags exist

Closes #2035
