minor : fixes for ratoml module

[alibektas]

This is a follow-up PR to #17058.

• Parse errors are reflected as such by defining a new variant called ConfigError::ParseError
• New error collection has been added to store config level agnostic errors.

EDIT : Some things that this PR promised to solve are removed and will be addressed by other PRs

	// FIXME: This should be an error
	[cargo.sysroot]
	non-table = "expected"

I would also like to ( since it is relevant to this issue ) ask why this is supposed to be an error. If my assumption is correct it is related to the hyphenated key. If that's the case toml actually allows such keys.

Sprry forgot to reply to this. the error here is that sysroot isn't a table config, so the the non-table key being used here should error
