Enable stream and file logs output

[KonstantinTyukalov]

PR is based on these changes: #4829

• Added --restreamlogstofiles command line option
• Added error output if both --restreamlogstofiles and --disableloguploads are used
• Added UTC timestamp to local file log lines in universal time format. Example format: 2024-08-01T12:01:40.3870840Z ...
• Updated --help docs for new option

I tested it with 3 cases:

1. --ReStreamLogsToFiles flag passed (should stream logs to server and store locally)
2. --DisableLogUploads flag passed (should store logs locally only)
3. no flags passed (should stream logs to server only

In all cases, the logic works as expected

We need the ability to stream the log as well as store it on the build agent's file system. The impact to us is that we need to limit jobs to 5k log lines and we don't have an easy mechanism to ship the logs to our own logging backend.

If we store the logs locally, we can then easily upload to our backend.

The reason for all this is that we constantly hit rate limits due to amount of log data we have to pull out.
