Soong config variables may propagate an uppercase name from Make.
Blueprint properties have traditionally been all lowercase, and
using an uppercase property struct field name resulted in a strange
Blueprint property name with the first rune lowercase and the
remaining runes uppercase.
Update the rules for proptools.PropertyNameForField to not lowercase
the first rune if the field name has mulitple runes and is not all
uppercase.

The proptools functions took an inconsistent variety of
struct and *struct types. Some methods even took a struct
but returned a *struct. Make all the exported methods
take a *struct, with internal helpers for the ones that need
to take a struct.

The filter tag is unused, replaced with FilterPropertyStruct to
generate a new type at runtime that only contains the filtered
fields.
