fix: rename patches/devtools_frontend to patches/devtools-frontend

[appdevopts]

Remove folder patches/devtools_frontend

Closes #42211.

This PR rename patches/devtools_frontend to patches/devtools-frontend, to resolve conflicts imported by prs:
#40413
#41895
#42103
#42093

There are no test folder in devtools-frontend in this branch, and patches for ChildTargetManager.ts have already been applied by #41895, so the patch #42103 could not be applied!
