[libc++] Build <filesystem> support as part of the dylib

Summary:
This patch treats <filesystem> as a first-class citizen of the dylib,
like all other sub-libraries (e.g. <chrono>). As such, it also removes
all special handling for installing the filesystem library separately
or disabling part of the test suite from the lit command line.

+* rXXXXXX - Integrate <filesystem> support into the shared library
+
+  This patch introduces support for <filesystem> into the shared library,
+  instead of requiring users to manually link against a static archive. As
+  such, new symbols required to implement <filesystem> are exported from
+  the shared library.
