  [Swift GTK] Use stamp for Swift generated header
https://bugs.webkit.org/show_bug.cgi?id=314445

Reviewed by Adrian Perez de Castro.

WebKit cmake builds will soon include a build step which outputs a header file
containing bindings to all WebKit's internal Swift APIs. This header file will
be frequently regenerated when any Swift file changes. As it will be included
in a fair number of C++ files, this will cause a fair number of extra C++ build
steps to occur. Yet frequently Swift changes won't cause differences in the
generated header file. This change adjusts the cmake rules to use a stamp file,
such that if the newly generated header file is identical to the previously
generated header file, it won't cause a rebuild of the C++ steps.

This change introduces a stamp file which is used for dependency tracking,
while not actually changing the generated header file timestamp if it's
unchanged.
