Revert "Add a build target and a proper export header for shared library builds."

This reverts commit 00334675c18a0203f313cceb670c970a77280f49.

Reason for revert: Breaking the deps roller - https://chromium-review.googlesource.com/c/609307

Original change's description:
> Add a build target and a proper export header for shared library builds.
> 
> This CL adds support for Chromium's component build feature to pdfium.
> 
> The export header stub in fpdfview.h is expanded to match Chromium's
> export mechanisms and patterns (fixes pdfium:825).
> 
> A component/shared library build can be triggered by adding
> 
> is_component_build = true
> 
> as a gn argument. Please note that setting this will also affect some
> of pdfiums dependencies like v8, which will be build as components
> too.
> 
> Additionally, this CL provides a "pdf_source_set" template which
> dynamically enables the use of "source_set" when building a complete
> static library or a shared library to reduce build time.
> 
> When testing this it is recommended to only build the pdfium target as
> most of pdfiums test rely on non-public functions which aren't exported
> by the shared library.
>
