The new file coverage metrics are available in all supported GHES
versions. This PR tags lines of code queries as telemetry queries. Lines
of code information will still be available in the SARIF file, but it
will no longer be displayed in the logging output of the CLI.
The one exception is the metric queries for Java/Kotlin that provides
separate lines of code information for Java and Kotlin. I've kept these
since separate file coverage information for languages like Java and
Kotlin is only available for GHES 3.12 and later.
Move the `lines-of-code` tag from `py/summary/lines-of-code`.
Code Scanning will eventually look for this tag.
The intent is to treat the number of lines of user code for Python as the summary of
how much code was analysed, ignoring both external libraries and generated code.
This matches the current baseline metric the CodeQL Action computes for Python.
We'll revisit this decision, and the baseline, if necessary.
