Subject: [PATCH 5/9] scripts: python: implement function for thread creation

Create a thread with the specified name, process ID (pid),
and thread ID (tid). The function initializes markers,
samples, frameTable, and stackTable structures for the thread.

The markers structure defines the schema and data for thread
markers, including fields such as 'name', 'startTime',
'endTime', 'phase', 'category', and 'data'.

The samples structure defines the schema and data for thread
samples, including fields such as 'stack', 'time', and 'responsiveness'.

The frameTable structure defines the schema and data for frame
information, including fields such as 'location', 'relevantForJS',
'innerWindowID', 'implementation', 'optimizations', 'line',
'column', 'category', and 'subcategory'.

The purpose of this function is to create a new thread structure
with the necessary data schemas and initial data arrays. These
structures provide a framework for storing and organizing information
related to thread markers, samples, frame details, and stack information.
