wolfssl: tls early data support

Enable TLS Early Data for wolfSSL:

- merge WOLFSSL_CTX and WOLFSSL setup from ngtcp2 with the general
  implemenation in wolfssl.c
- enable for QUIC via ngtcp2
- give Curl_vquic_tls_init() a `struct alpn_spec` like used for the TCP
  case. Adapt gnutls and other users.
- enable pytest test cases for early data with wolfSSL

and while this messes up wolfssl.c anyway, do

- rename all struct/functions with prefix 'wolfssl_' to 'wssl_' to not
  pollute that name prefix
- rename `ctx/handle` to `ssl_ctx/ssl`, as used in openssl case
