[vm] Intern callstacks when writing Perfetto profile

This significantly reduces the space occupied by callstacks
e.g. 5 second recording of fibonacci computation goes from
1.5Mb to 600Kb.

Also fixes flakiness of pkg/vm_service/test/get_perfetto_cpu_samples_rpc_test.

Fixes https://github.com/dart-lang/sdk/issues/54401
Fixes https://github.com/dart-lang/sdk/issues/60413

This relands commit f07915cb6e9da7efd5ad66a81d597ec5fa595440
with a fix for Android build.

TEST=ci
