fix(test_apps): Trim builds of component test apps

Some component test apps do not use the "set(COMPONENTS main)" command in their
project level "CMakeLists.txt", thus leading to their builds pulling in all
ESP-IDF components.

This commit trims the build of multiple component test apps:

- Add "set(COMPONENTS main ...)" to project level "CMakeLists.txt"
- Add missing "PRIV_REQUIRES" in some "main" component "CMakeLists.txt"

Also removed repeated configuraiton options in legacy_i2c_driver/sdkconfig.ci.defaults
as they are already specified in legacy_i2c_driver/sdkconfig.defaults
