LP1834665 Import marcrecord.js to Angular

Port the marcrecord.js file into the Angular build configuration so it
may be used by the MARC editor code.

Additionally, port jquery-dependent code to vanilla JS to avoid the
jquery dependency.  As a part of this, some code from the source file
was removed since it was not needed (yet, anyway).  Code added back will
need to be similarly ported (mostly changing XML parsing).

Note as-is, the JS is loaded on every Angular page.  We could optimize
this and have it loaded only when needed if we port it to Typescript and
integrate it into the application instead of loading it as a 3rd-party
dependancy.
