…ents to use list and uploader components inside of the AttachmentsDropZone slot

- removed unused styled in AttachmentsList

- added missing closing quotes to drag-dropped and content-changed event handlers

- working, but with what feels like more re-renders than necessary, and so wondering if we can cut down on those
- also wondering if AttachmentsList should be it's own separate component or just implemented as part of whatever component is using the AttachmentsDropZone and AttachmentsUploader components

- updated handleAttachmentsAdded to do one requestUpdate for attachmentsList instead of two separate updates (one for currentAttachments, one for failedAttachments)
- added requestUpdate for attachmentsUploader in handleAttachmentsRemoved

- moved attachment interface from Attachments to AttachmentUploader
- removed attribute: false from failedAttachments properties across all 3 components

- added two image-pickers to demo page, one for avatars, one for logos
- added vector icons for avatars and logos
- added removeIcon property for configuring remove icon
- added uploadIcon property for configuring upload icon
- added default upload_icon and max_attachments to AttachmentsUploader
- reworked uploadFiles to check for when maxAttachments is 1
- reworked uploadFiles to check whether the total of currentAttachments and filesToUpload exceeds maxAttachments and to adjust the filesToUpload to only allow up to maxAttachments (assuming all of the filesToUpload will be successful)
- updated addCurrentAttachment and addFailedAttachment to check for maxAttachments
- updated render to check for maxAttachments and render the input as single vs multiple when 1 vs 1+
