[sqlite] Respect the gyp and gn component switch.

[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.

Apologies for the steampunk nature of the SQLITE_API defines - I was not able to
find appropriate examples in the codebase, all of our code seems to do it like
sql/sql_export.h, which would require additional patching of SQLite.  I _think_
this ends up the same.
