chore: create main rc workflow

[sethkfman]

Description

The mobile app doesn't currently support rc feature flags. This is important to enable flag testing in release candidate builds. Two new workflows have been added to enable RC builds and will need to be integrate into the Runway workflow.

• build_android_rc_and_upload_sourcemaps
• build_ios_rc_and_upload_sourcemaps

Manual testing steps
