This reverts commit 2115ba50.

Reason for revert: Breaking Blink tests.

Original change's description:
> [cppgc-js] Allow overriding marking support
>
> Adds flags to allow overriding marking support. This adds
> compatibility with EmbedderHeapTracer which allows for disabling
> incremental marking support with `--no-incremental-marking-wrappers`.
>
> The corresponding CppHeap flags are
> * `--cppheap-incremental-marking`
> * `--cppheap-concurrent-marking`
>
> This allows embedders that use types that do not support incremental
> and concurrent marking to switch from EmbedderHeapTracer to CppHeap.
