Distribute centralized files like consolidated-tools.json into tools/ directories #1333
Description
As part of the original Areas migration (Azure/azure-mcp#426), a lot of work was done to remove any files that had to be updated every time a tool was added.
It seems we've regressed back to central tool files:
consolidated-tools.json
prompts.json
namespace-tools.json
consolidated-prompts.json
It looks like the data in these files could be divided into the tools/ directories instead of being centralized.
If not distributed, the files in the eng/ directory should be moved to the Azure server or core directory as they don't apply to all servers in the repo.
