Tess Strickland 9df6656aa9 [build] Re-add linker flags to create empty section in AOT runtime.
To avoid these flags being applied to unexpected build rules, we
separate them out into a separate config that is then pulled in
explicitly in the `dart_precompiled_runtime{,_product}` executable
rules. Only those two executables need the additional empty section:
the product version because it becomes `dartaotruntime` in the SDK
bundle, and the non-product version because some of our tests build
standalone executables using it.

The linker flags were originally removed due to
https://github.com/flutter/flutter/issues/112687.
With the recent removal of bitcode support from Flutter (see
https://github.com/flutter/flutter/issues/107883), I can build
the `ios_release` target locally without any issue.

This also reverts the clang DEPS changes from CL 256208 (again).
