Remove io.netty.http2.validateContentLength SystemProperty (#11561) 

Motivation:
io.netty.http2.validateContentLength SystemProperty was added as a way
to opt-out for compabitility for libraries/applications that violated
the RFC's content-length matching requirements [1] but have not yet been
fixed. This SystemProperty has been around for a few months now and it
is assumed these issues have now been addressed in 3rd party code.

[1] https://tools.ietf.org/html/rfc7540#section-8.1.2.6

Modifications:
- Remove the io.netty.http2.validateContentLength SystemProperty,
  preventing folks from opting out of RFC's required content-length
  matching.

Result:
No more escape hatch in H2 for content-length matching enforcement.
