feat: Added CCPA consent support

[ngarg-mparticle]

Summary

Since the format of consent data expected by mParticle is the same for GDPR and CCPA, the class GDPRConsentState was renamed to a more regulation-agnostic name ConsentPurpose and refactored accordingly

Testing Plan

Tested by adding this code to MainActivity.java in the sample app, just before the uploadEvents call in run() method:

                    // CCPA Consent State
                    ConsentPurpose purpose = new ConsentPurpose();
                    purpose.setConsented(true);
                    purpose.setDocument("test_document");
                    purpose.setHardwareId("test_hardware_id");
                    purpose.setLocation("test_location");
                    purpose.setTimestampUnixtimeMs(System.currentTimeMillis());

                    ConsentState consentState = new ConsentState();
                    consentState.setCcpa(purpose);

                    batch.setConsentState(consentState);

Verified that mP received and processed the consent information successfully by checking "Event Data" in Live Stream and "Consent and Compliance" section in UAV
