`pyproject.toml` for Flet project metadata, running and building settings

[FeodorFitsner]

flet run CLI commands have a lot of options right now, especially flet build.

New controls/packages require even more settings, options, variables, etc.

We are going to use pyproject.toml with tool.flet.* tables for Flet-specific stuff.

pyproject.toml will be created with flet create command as part of the new project.

A new flet init command will be added to generate pyproject.toml file.

Flet's pyproject.toml reference (we are going to list only settings required for Flet CLI):

[project]

# ...TBD

[tool.flet]

# ...

[tool.flet.ios]

# ...

[tool.flet.android]

# ...
