[XRay] Define the library for XRay trace logs Summary: In this change we move the definition of the log reading routines from the tools directory in LLVM to {include/llvm,lib}/XRay. We improve the documentation a little bit for the publicly accessible headers, and adjust the top-matter. This also leads to some refactoring and cleanup in the tooling code. In particular, we do the following: - Rename the class from LogReader to Trace, as it better represents the logical set of records as opposed to a log. - Use file type detection instead of asking the user to say what format the input file is. This allows us to keep the interface simple and encapsulate the logic of loading the data appropriately. In future changes we increase the API surface and write dedicated unit tests for the XRay library. Depends on D24376.

[XRay] Implement `llvm-xray convert` -- trace file conversion This is the second part of a multi-part change to define additional subcommands to the `llvm-xray` tool. This change defines a conversion subcommand to take XRay log files, and turns them from one format to another (binary or YAML). This currently only supports the first version of the log file format, defined in the compiler-rt runtime. Depends on D21987.

Disable wrapping llvm-xray YAML output Summary: The YAML output produced by llvm-xray is supposed to be wrapped at the arbitrary default of 70 columns set by `yaml:Output`. Unfortunately, the wrapping is rather unpredictable, and can easily go past the set number of columns, depending on the execution environment. To make the YAML output environment-independent, disable wrapping instead.
