QSslCertificate: add fromFile() method

QSslCertificate::fromPath() does some extra work:
- matching wildcard glob or regular expression patterns
- checks if the string it's called on is a file or a dir

That extra work isn't needed when you already have the path to a
specific certificate file.
E.g. qtlsbackend_openssl.cpp:systemCaCertificates() used to call
fromPath() on *.pem/*.crt files that it got from iterating over system
certifcates dirs.

This also de-duplicates the code in fromPath().

[ChangeLog][QtNetwork][QSslCertificate] Added fromFile() method.
