**Description:**
This PR removes the top level if/else in `component.UnmarshalConfig`,
handling recursive state in the confmap.Conf object instead.
This PR deprecates `component.UnmarshalConfig` in favor of calling
directly `Unmarshal` on the confmap.Conf object.

**Description:**
This adds a decode hook for unmarshalling negative integers into uint
types. This will now return an error instead of converting negative
values into large uint values.

Fixes#9060
**Testing:**
Added unit tests for confmap functionality, functional tests in memory
limiter processor (the original component this issue was filed against)
**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.

**Description:**
Following
https://github.com/open-telemetry/opentelemetry-collector/issues/8632,
this change introduces memory limiter as an extension. This allows
us to place the component to reject incoming connections due to limited
memory, providing better protection from running out of memory.
missing feature: receiver fairness. issue where a receiver hogs all the
resource can happen.
