Port MemcachedBackend from master to 3_7_6
Use the newest version of MemcachedBackend as PHP7 doesn't support "Memcache", but only "Memcached".

[FEATURE] Support pecl-memcached in MemcachedBackend
The MemcachedBackend now also supports the pecl-memcached
module. The caching backend detects which modules are installed
and uses "memcache" over "memcached" to avoid being a breaking
change. If both modules are installed, an integrator can choose the
PECL module by setting the new ``peclModule`` option.
This feature was originally introduced with TYPO3 v8.0. Due to
compatibility reasons with PHP 7 this feature gets backported as the
memcache module is not available anymore.
