Device and gpu protocols updated; public IJsonSerializable

[semuserable]

Related to getsentry/sentry-unity#49, check latest comment (which starts with 'Proposed changes').

I made IJsonSerializable public, because we'll have a new context on Unity side. Although, I'm not sure about summary description.

I also plan to update the docs, but after this part will be merged.

I plan to update the tests too. Still WIP.

Added the tests. Please, review @Tyrrrz @bruno-garcia as I'd like to start the integration on Unity side for these protocols.

Also, why danger fails again?

Please consider adding a changelog entry for the next release.

Instructions and example for changelog
Please add an entry to CHANGELOG.md to the "Unreleased" section. Make sure the entry includes this PR's number.

Example:
Device and gpu protocols updated; public IJsonSerializable([#1063](https://github.com/getsentry/sentry-dotnet/pull/1063))
If none of the above apply, you can opt out of this check by adding #skip-changelog to the PR description.

Perhaps using const names for the field names, for example:

internal const string ProcessorCountKey = "processor_count";
...
if (ProcessorCount is {} processorCount)           
 {                
writer.WriteNumber(ProcessorCountKey , processorCount);           
 }
...
var processorCount = json.GetPropertyOrNull(ProcessorCountKey)?.GetInt32();

var processorCount = json.GetPropertyOrNull(ProcessorCountKey)?.GetInt32();

I was relying on the current style. I haven't seen such usage from within the project, so used directly.
