Write the Precision Tracks out to the EDM

Currently TRT extension only enabled for the electrons. Code to enable this by default for all signatures is included but the TRT ByteStream service is giving errors for multiple slices, so this is disabled by defaul except for the electron slice and will be re-enabled in a later merge request.

Code to write out the Precision Tracks to the EDM as in MR !31621 (closed) is also included.

This does not fully map all the Tau instances, since there may be some tidy up in the proliferation of different tau related values for the signature variables that needs clarification from the tau side before this can be properly addressed.
