Add support for multitype imports, object literals, and object literals with aliases

[traceyyoshima]

Add LST elements to support the following imports:

    @Test
    void importObjectLiteral() {
        rewriteRun(
          javaScript(
            """
              import { First , Second , Third } from 'target';
              """
          )
        );
    }

    @Test
    void mixedTypes() {
        rewriteRun(
          javaScript(
            """
              import nameA , { First , Second } from 'targetA';
              """
          )
        );
    }

    @Test
    void multiAlias() {
        rewriteRun(
          javaScript(
            """
              import { FormData as FormDataPolyfill , Blob as BlobPolyfill , File as FilePolyfill } from 'formdata-node'
              """
          )
        );
    }
