Part of the code required to better support Module Federation/Micro Frontends.

The webpack bundler will be able to optionally inject metadata into each bundle chunk (getsentry/sentry-javascript-bundler-plugins#334).

This PR adds code that:

  • Adds module_metadata to StackFrame
  • Adds getMetadataForUrl that gets metadata for a path/URL
    • Parses the stacks on demand to get the relevant filename for a chunk and associated injected metadata
  • Adds addMetadataToStackFrames that populates module_metadata in stack frames with metadata when available
  • Adds stripMetadataFromStackFrames that strips module_metadata from stack frames

Add `<meta>` tag injection in our new `handleRequest` Astro
middleware to enable distributed traces between BE and FE transactions.

This is also the first step towards exporting a `<meta>` tag helper
function (tracked in #8438). In a future PR I'll extract the function to
the core or utils package and export it in our server-side SDKs.
