Unify sources for bindings more densely
https://bugs.webkit.org/show_bug.cgi?id=202918

Reviewed by Simon Fraser.

Source/WebCore:

No new tests, just a build time speedup.
For me, this is a reliable 17% boost on the WebCore Build Time Benchmark.

* Scripts/generate-unified-sources.sh:
Use dense bundles for JS* and bindings/js/*.
This seems acceptable for a few reasons:

- most of the time building these files is spent parsing the exact
same set of JSC headers, because the generated bindings code ends
up including the same set of things

- the incremental build cost of bundling more bindings sources together
is small, because the JSC headers dominate the time

- folks will frequently have to rebuild all of the bindings (on every
pull, for example, because they indirectly include most JSC headers),
but rarely end up rebuilding only a single one (in my experience)

* bindings/js/ReadableStreamDefaultController.cpp:
(WebCore::readableStreamCallFunction):
(WebCore::ReadableStreamDefaultController::invoke):
(WebCore::callFunction): Deleted.
Deduplicate static functions that now get bundled together.

* platform/graphics/ca/PlatformCALayer.cpp:
(WebCore::PlatformCALayer::currentTimeToMediaTime):
* platform/graphics/ca/PlatformCALayer.h:
In older macOS SDKs, CABase.h included ApplicationServices.h, which
causes lots of trouble.

Source/WTF:

* Scripts/generate-unified-source-bundles.rb:
Add an option to separate and more densely unify sources that match
a given glob pattern.
