test(bug): txtar to reproduce node crash on inserting many posts

[jefft0]

This txtar uses r/demo/boards to create a new board and post. Then it runs a script to add 800 replies (inserting into the avl.Tree). To run the test:

go test -v -count=1 ./gno.land/pkg/integration --run TestTestdata/many_inserts_stack_overflow

This should succeed. (There is enough gas.) But the node becomes unresponsive. (In some tests, when I run the script in a terminal with gnokey and a gnoland node, it crashes with "fatal error: stack overflow".) See the gist with the stack dump.

As the txtar says, if it only adds 600 replies then it succeeds.

NOTE: This PR also has a commit with the fix in #4435 to allow maketx run to call a crossing function. When that PR is merged, this commit will be removed from this PR.
