Add WRITE_FILE function to trace_processor

Add a function to write a blob to a file. This gives us an easy way of
writing profiles generated with EXPERIMENTAL_PROFILE into a file.

Added a new helper method OpenFstream that takes care of Windows'
special treatment of filenames (wrt character encoding). Used this new
function in ExportJson SQL function which as a bonus fixes a FILE* leak
