feat(DX): PEP517 compatible build in new apps

[ankush]

closes #21612

PIP will overtime move away from setup.py installs completely, so if you maintain Frappe app it's wise to add pyproject.toml file. Copy Frappe's and modify values if you're unsure how to do it.

frappe/pyproject.toml

New apps created with/for v14 don't get a pyproject.toml yet, which can cause issues already. Hence, I suggest backporting this.
