gcc/clang (-fvisibility=hidden): corrections to compile and work properly (#4394)
* fix(ActiveRecord): missing ActiveRecordLib_API definitions for clang/gcc.

* fix(FPEnvironment): export FPEnvironmentImpl classes (#4393, #3331)

* fix(Crypto): export *Impl classes used from inlines (#4393, #3331)

* fix(Dynamic): explicitly instantiate and export Dynamic::Struct for string and int (-fvisibility=hidden) (#4393, #3331)

* fix(JSON): explicitly instantiate and export SharedPtr for JSON::Array and JSON::Object (-fvisibility=hidden) (#4393, #3331)

* enh(CMake): Set symbol visibility to hidden (#4393, #3331)

* enh(configure): user c++17 standard for iphone, Darwin and ARM-Linux.

* fix(UTF): explicitly instantiate and export 16 and 32-bit strings (-fvisibility=hidden) (#4393, #3331)

* fix(RecordSet): make Extraction.h internal and instantiate RecordsSet::column template functions only for supported types. (-fvisibility=hidden) (#4393, #3331)

* fix(UTF): fix explicitly instantiation on Windows (-fvisibility=hidden) (#4393, #3331)

* enh(CMake): Add github jobs for macOS with visibility set to hidden (#4393, #3331)

* fix(CppParser): Add missing declarations for CppParser_API (#4393, #3331)

* enh(CMake): Enable more options in github jobs for macOS with visibility set to hidden (#4393, #3331)

* fix(MongoDB): Add missing MongoDB_API (#4393, #3331)
