Support authentication using encoded certificate bundle directly: [client_certificate]

[loomkoom]

Description

The azapi provider documentation mentions that it supports service principal authentication using client certificates by using the client_certificate_path, which contains the path of a .pfx/.p12 file.

However, passing the client-certificate base64 encoded to the client_certificate value like in azurerm and azuread doesn't seem to be supported.

It would be nice for the azapi provider to also support this method of authentication through the extra client_certificate argument.
