The motivation for this is first that under some combinations of flags it breaks builds and second it's trivial (and possibly zero runtime cost) to fix.
It looks like the possibly bad case "should never happen", but converting this to a null pointer in the error case (which should at least make the failure less problematic) is cheap.

Without this change, an input of `9223372036854775807, 2` leads to a java.lang.ArithmeticException: overflow.

My org, as part of its reproducible-build hygiene, builds projects with the source trees in read-only mode. I approached the protobuf build in the same way, but encountered this error (among others):

(`/home/src` is a read-only mount)
Generated source files are effectively build artifacts, and should be written to the build tree, not the source tree. This PR accordingly enables a successful build and test run (lite, full, and conformance) with read-only sources.
(Beyond this, I would add that CMake usually does not need source file paths to be qualified with `CMAKE_SOURCE_DIR` or `CMAKE_BINARY_DIR`; in most cases it knows to look in both locations, favoring the latter if a file is in both. The CMake code could be simplified by relying on this behavior.)

We recently updated the codebase to comply with the Bazel layering check, which
essentially requires any C++ header inclusion to be matched with a build
dependency on a target providing that header.
As part of that, I removed a handful of dependencies from the `//:protobuf`
target, since these dependencies were not set up in a way that respected the
layering check. However, I realized that this may cause a number of breakages,
especially since we did not provide the correct public targets until very
recently.
This change effectively adds back in the missing dependencies, so that projects
which do not yet adhere to the layering check can continue to depend on them
indirectly. This way, we still adhere to the layering check and make it
possible for projects that depend on us to do so, but in most cases we won't
immediately break anyone.

WriteDictionary does not pass indentationLevel downwards to WriteValue. The existing test for `MapField` only tests `MapField<string, string>`, which isn't affected by the issue.
Tests are added for this issue.
Note: I also added `WriteValueWithIndentation_MapWithEmptyNested` to ensure this change would break things, but I doubt if it's necessary. Let me know whether to remove it.

Useful for test non-codegen types that have their own parsing logic.
Also forward the `ptr` through the post_loop_handler to allow it to fail.

`_InternalParse` implementation to use it.
For LITE messages, populate the entry in `ClassData` and remove the override for
`_InternalParse`.
