Add excludeExceptionFilePathPrefixesByErrorLevel option

[MiauzGenau]

for more granular control over which exceptions to exclude.

We would like to exclude all 'Warnings' from third party packages.
This is an idea to enable that, with a configuration option like this:

Flownative:
  Sentry:
    capture:
      excludeExceptionFilePathPrefixesByErrorLevel:
        'E_WARNING | E_DEPRECATED | E_USER_DEPRECATED':
          - 'Packages/Libraries/'
