feat: update user configuration example and add development package support

- Enhanced the user.depot.toml.example file with additional comments and options for user-local preferences.
- Bumped version from 0.35.0 to 0.35.1 in meson.build.
- Introduced a new option for DEPOT_DEVELOPMENT_PACKAGE in meson_options.txt.
- Added functions to handle the requested development package in build_options.rs.
- Updated various builder files (autotools.rs, cmake.rs, custom.rs, meson.rs, perl.rs) to support passing build flags.
- Implemented checks for the required development package during source builds in commands.rs and commands/build_cmd.rs.
- Added tests to ensure the correct behavior of development package requirements and source build warnings.
- Modified manual source handling in source/mod.rs to validate local manual sources before proceeding with builds.
- Updated cargo build and test scripts to accept a new development package argument.
- Added VSCode settings to disable automatic configuration on open.
