Add support for pubspec overrides file (#3215)

This change adds support for a new file pubspec_overrides.yaml to override parts of pubspec.yaml. Overrides are only active for the get and upgrade commands.

An overrides file has the same structure as pubspec.yaml, but only supports a subset of its fields. Currently, only the following top-level field override pubspec:

dependency_overrides
All other fields in the overrides file causes an error.

A dependency_overrides, in the overrides file, completely replace a dependency_overrides in pubspec.yaml. The two files are merged in a way that preserves source references to provide correct error messages.

When overrides are active, a warning is logged.

Fixes #2161 .
