Update library licenses

Description

This MR is a minor update to the list of libraries shown in the About screen. A larger library review will occur under !1553 (merged).

The following modifications are included in this change:

1. Reformat JSON file for readability (whitespace only)
2. Alphabetize the list of licenses
3. Clean-up spacing for the numbered list in the zlib license
4. Fix typographical issues with the GSM license
5. Add Apache 2.0 license for AOSP

How Has This Been Tested?

File loads as expected, Apache license is shown for AOSP, and small formatting issues (gsm, zlib) are resolved.

Types of changes

• Enhancement (non-breaking change which cleans up / improves existing functionality)
