Add INLINE and INLINE_ORIGIN records on Windows dump_syms
This adds INLINE and INLINE_ORIGIN records on Window dump_syms. It also adds more LINE records that represents the inner most callsite line info inside a function. Bug: chromium:1190878 Change-Id: I15c2044709f8ca831b03a453910d036f749452c6 Reviewed-on: https://chromium-review.googlesource.com/c/breakpad/breakpad/+/3133606 Reviewed-by: Lei Zhang <thestig@chromium.org> Reviewed-by: Joshua Peraza <jperaza@chromium.org> Reviewed-by: Ivan Penkov <ivanpe@chromium.org>
