OHOS CI: Allow benchmarking of files and show smaps (#37881)

OHOS CI: Now we can benchmark specific files. These files need to be in
the runs.json and in the supprt/hitrace-bench folder.
A simple testcase of parsing html from string is included (taken from
https://github.com/servo/servo/issues/37223).
We copy all files in
support/hitrace-bench into the hap of the phone.
These files can use the console.log javascript command to get their
measured output.

Additionally, this now supports reporting resident-accordings-to-smaps
which is a slightly different memory than resident.

This needs update to hitrace-bench 0.7 which will be completed once the
PR is marked ready.

Testing: On action runner here:
