REGRESSION(302916@main): [GTK][WPE] UIProcess stuck during SQLite
initialization
https://bugs.webkit.org/show_bug.cgi?id=302452
Reviewed by Carlos Garcia Campos.
In 302916@main a workaround was added to do arrange calling
sqlite3_initialize() in the main thread but this causes issues
with the WPE (less often) and GTK ports (almost always) because
there are some public API functions that may result in initializing
databases while the main loop is not yet running, resulting in UI
process lockups waiting for initialization to complete.
The workaround is needed on Darwin because sqlite3_initialize() ends
up calling confstr() to determine a temporary directory, which will
access (and even write) to environment variables, which is notoriously
not thread-safe. But on supported non-Darwin systems, confstr() is
either unavailable or MT-safe, so we can wrap the workaround inside
an OS(DARWIN) guard.
