**Description:**
- Adds `component.MustNewType` to create a type. This function panics if
the type has invalid characters. Add similar functions
`component.MustNewID` and `component.MustNewIDWithName`.
- Adds `component.Type.String` to recover the string
- Use `component.MustNewType`, `component.MustNewID`,
`component.MustNewIDWithName` and `component.Type.String` everywhere in
this codebase. To do this I changed `component.Type` into an opaque
struct and checked for compile-time errors.
Some notes:
1. All components currently on core and contrib follow this rule. This
is still breaking for other components.
2. A future PR will change this into a struct, to actually validate this
(right now you can just do `component.Type("anything")` to bypass
validation). I want to do this in two steps to avoid breaking contrib
tests: we first introduce this function, and after that we change into a
struct.
