ECH: enable support for the AWS-LC backend
Extend existing ECH support for BoringSSL to its AWS-LC fork. Also enable ECH in AWS-LC CI jobs. ``` curl 8.11.0-DEV (x86_64-pc-linux-gnu) libcurl/8.11.0-DEV AWS-LC/1.37.0 zlib/1.3 brotli/1.1.0 zstd/1.5.5 libpsl/0.21.2 Release-Date: [unreleased] Protocols: dict file ftp ftps gopher gophers http https imap imaps ipfs ipns mqtt pop3 pop3s rtsp smb smbs smtp smtps telnet tftp ws wss Features: alt-svc AsynchDNS brotli ECH HSTS HTTPS-proxy IPv6 Largefile libz NTLM PSL SSL threadsafe UnixSockets zstd ``` Closes #15499
