// * The variant property structs are analysed to find exported (capitalized) fields which
// have common values. Those fields are cleared and the common value added to the common
// properties.
//
// A field annotated with a tag of `sdk:"keep"` will be treated as if it
// properties. A field annotated with a tag of `sdk:"keep"` will be treated as if it
// was not capitalized, i.e. not optimized for common values.
//
// A field annotated with a tag of `android:"arch_variant"` will be allowed to have
// values that differ by arch, fields not tagged as such must have common values across
// all variants.
//
// * Additional field tags can be specified on a field that will ignore certain values
// for the purpose of common value optimization. A value that is ignored must have the
// default value for the property type. This is to ensure that significant value are not
// ignored by accident. The purpose of this is to allow the snapshot generation to reflect
// the behavior of the runtime. e.g. if a property is ignored on the host then a property
// that is common for android can be treated as if it was common for android and host as
// the setting for host is ignored anyway.
// * `sdk:"ignored-on-host" - this indicates the property is ignored on the host variant.
//
// * The sdk module type populates the BpModule structure, creating the arch specific
// structure and calls AddToPropertySet(...) on the properties struct to add the member
// specific properties in the correct place in the structure.
