change(conf): add MINIMAL_BUILD note to menuconfig and sdkconfig

Browse Source 
With MINIMAL_BUILD enabled, menuconfig will only display configuration
options for components included in the build through main component
dependencies. This means that configuration options for excluded
components will not appear in menuconfig. This might be confusing, as
most examples currently do not use a trimmed build, and all components
detected by the build system are available in menuconfig, even if their
configuration has no effect because the components may not be linked or
used. Adding a note in the components menu of menuconfig could help
users realize they need to add a component to the main component
requirements to see its configuration options. Unfortunately, Kconfig
does not support multiline comments, so there are three separate
comments intended to adequately describe the potentially missing
component configurations.
