[FEATURE] Improve creation of URL query strings from arrays

Adds a new method HttpUtility::buildQueryString() using
http_build_query() instead of reimplementing the encoding-process like
the old method GeneralUtility::implodeArrayForUrl() did.

As the parameter $rawurlencodeParamName of implodeArrayForUrl() was set
to "false" by default and used in several places without manually
setting it to "true" using that method could lead to potentially unsafe
non-encoded parameter names.

Some unit-tests had wrong URLs with non-encoded braces [...], which were
adapted to be properly escaped as well.
