Revert of [sqlite] Respect the gyp and gn component switch.

Revert of [sqlite] Respect the gyp and gn component switch. (patchset #6 id:100001 of https://codereview.chromium.org/1306863006/ )

Reason for revert:
Suspected of breaking chromium.webkit Mac builders, see https://code.google.com/p/chromium/issues/detail?id=526208

Summary:

Incompatible library version: httpd requires version 9.0.0 or later, but libsqlite3.dylib provides version 0.0.0

/b/build/slave/WebKit_Mac10_6__dbg_/build/src/out/Debug/libsqlite3.dylib seems to be used instead of expected/intended /usr/lib/libsqlite3.dylib

Original issue's description:
> [sqlite] Respect the gyp and gn component switch.
>
> SQLITE_API is the existing mechanism SQLite provides, and is used in
> preference to inventing a new SQLITE_EXPORT symbol (like
> sql/sql_export.h and other examples).
>
> CoreServices.framework is necessary on OSX because of the Time Machine
> patch.
>
> Remove sql/proxy.{h,cc}, which was necessary to work around SQLite
> linking statically into both component shlibs and unit test executables.
