  [SPI Checking] Store soft-linking constant strings in a separate binary section

Reviewed by Alexey Proskuryakov.

As part of an ongoing project to analyze WebKit use of SPI at build
time, we need a way to detect use of soft-linked SPI. Since the vast
majority of soft-linking in WebKit is done via the <wtf/SoftLinking.h>
library, change its macros to emit dlsym and objc_getClass string
constants to their own respective sections of the __TEXT segment.
This enables auditing tools to analyze possible usage by dumping the
contents of the section.
