WasmFS: Add metadce tests for WasmFS and file operations (#19502)

kripken · web-flow · commit b87f15a0b37d · 2023-06-01T17:22:34.000-07:00
A new metadce test uses file read and write operations, so we can measure the
size of programs using the filesystem.

_wasmfs modes are added to other key metadce tests to be able to track WasmFS
size (I will be opening PRs to improve things).

Minor NFC refactor of test_metadce_libcxxabi_message which I just noticed could
be a little simpler in the python code.
