A very simple solution is to assign a function to the click event of the desired element and control the value of the display attribute of the form. To do this, you can use a control variable that defines whether or not the form is visible, by always reversing this variable in the link event.

See an example below:

// Objetos do DOM:
const link = document.querySelector(".menu_propaganda_guia_comercial_exibir");
const form = document.querySelector(".frm_enviar_email_gc");

// Variável que define se o formulário está, ou não, visível:
let formIsVisible = true;

// Controla o evento 'click' do link:
link.addEventListener("click", function (event) {

  // Inverte o estado do formulário:
  formIsVisible = !formIsVisible;

  // Atualiza o valor da propriedade de acordo com o novo estado:
  form.style.display = (formIsVisible ? "block" : "none");

});

<nav class="menu_propaganda_guia_comercial">
  <ul>
    <li><a class="menu_propaganda_guia_comercial_exibir" href="#" title="Enviar e-mail">Enviar e-mail</a></li>
    <li><a href="#" title="Mais detalhes">Mais detalhes</a></li>
  </ul>
</nav>

<form class="frm_enviar_email_gc" action="#" method="post">
  <h3>Solicitar Orçamento:</h3>
  <input type="text" id="solicitacao_nome" class="intrada_frm_enviar_email_gc" placeholder="Nome">
  <input type="email" id="solicitacao_email" class="intrada_frm_enviar_email_gc" placeholder="Email">
  <input type="text" id="solicitacao_telefone" class="intrada_frm_enviar_email_gc" placeholder="Telefone">
  <textarea class="intrada_frm_enviar_email_gc" id="solicitacao_msg" placeholder="Mensagem"></textarea>
  <button class="intrada_frm_enviar_email_gc_enviar" type="submit">Enviar sua solicitação</button>
</form>
