asn1write: Test short and large buffers more systematically
Use the test-many-sizes framework for string writes as well (previously, it was only used for booleans and integers). This way, more edge cases are tested with less test code. This commit removes buffer overwrite checks. Instead of these checks, run the test suite under a memory sanitizer (which we do in our CI).
