[FileCollector] Move interface into FileCollectorBase (NFC)

For the reproducers in LLDB we want to switch to an "immediate mode"
FileCollector that writes every file encountered straight to disk so we
can generate the actual mapping out-of-process. This patch moves the
interface into a separate base class.
