feat: Add Remix SDK

[onurtemizkan]

Ref: #4894

Example project: https://github.com/onurtemizkan/remix-blues-with-sentry

Client side

• Uses React SDK underneath, and requires <ErrorBoundary /> to properly catch errors.
• Supports parameterized route paths with remixRouterInstrumentation and withSentryRouteTracing.

Tested:

• Router Tracing with Parameterized Paths -> Link to Transaction
• Error Tracking (only with ErrorBoundary) -> Link to Event
• Web Vitals

Server side

• Uses Node SDK underneath.
• For tracing, monkey-patches createRequestHandler from @remix-run/server-runtime which apparently is used by all server-side adapters of Remix.
• action and loader functions are patched as parameters of createRequestHandler.

Tested:

• Tracing action / loader
• Tracing requestHandler
• With Prisma spans
• Error Tracking

Link to Transaction
Link to Event

TODO

• Sourcemaps
• Add README
• Add docs
• Increase Test coverage
• Integration tests

@onurtemizkan skimmed through the PR and looks great!

I would like us to split this up for ease of review and tracking through GH. Let's open PRs for the following:

1. Have a PR that just adds the Remix SDK package boilerplate (setups up folder structure) - but has nothing in src/* or test/*
2. PR that adds client-side support with tests
3. PR that adds server-side support with tests
4. Sourcemaps support
5. PR for README
6. Integration tests for Remix
7. PR for sentry-docs

I'm going to update #4894 with these details!
