* Use url.PathUnescape rather than url.QueryUnescape
I believe this addresses the majority of the cases described in
https://github.com/open-telemetry/opentelemetry-go/issues/3601
Golang's url.QueryUnescape will render url _path_ elements (e.g. /, +)
as spaces: `foo+bar` is rendered as `foo bar`. Path elements are (as I
read the spec) legal W3C baggage values, and replacing them with spaces
fails the value validation regex.
url.PathEscape allows path elements through unmolested.

* Fix baggage.NewMember to decode the accepted value
`value` is decoded and stored after validating the input parameters.
Corresponding test cases are modified so that we can make sure `value` is properly encoded before creating Member.
* fix md lint
* add function document to NewMember for value encoding and decoding
* remove redundant comments and fix CHANGELOG.md
* fix wrong PR number in the changelog
* fix wrong PR number
* fix md-lint

* use NewMember, or specify if the member is not validated when creating new ones
* expect members to already be validated when creating a new package
* add changelog entry
* add an isEmpty field to member and property for quick validation
* rename isEmpty to hasData
So by default, an empty struct really is marked as having no data
* Update baggage/baggage_test.go

* don't validate the member in parseMember, we alredy ran that validation
We also don't want to use NewMember, as that runs the property
validation again, making the benchmark quite slower
* move changelog entry to the fixed section
* provide the member/property data when returning an invalid error
