Move db bundler group to metasploit-framework-db.gemspec

MSP-11578

This will allow Metasploit Pro to use the
metasploit-framework-db.gemspec to ensure it has the correct version of
gems that were previously only in metasploit-framework's Gemfile and so
weren't being checked for version compatibility when Pro used
metasploit-framework.gemspec.
Explicitly require 'metasploit/credential' and 'metasploit_data_models'

By putting the db group into the metasploit-framework-db.gemspec,
bundler no longer automatically required 'metasploit/credential' and
'metasploit_data_models' because gems, such as metasploit-framework-db,
are expected to explictly require their dependencies.
Move pcap bundler group to metasploit-framework-pcap.gemspec

MSP-11578

This will allow Metasploit Pro to use the
metasploit-framework-pcap.gemspec to ensure it has the correct version of
gems that were previously only in metasploit-framework's Gemfile and so
weren't being checked for version compatibility when Pro used
metasploit-framework.gemspec.
Add metasploit-framework as dependency of metasploit-framework-pcap

MSP-11578

Any of the optional depenency gems should depend on the minimal
metasploit-framework as it supplies the versioning information.

Depend on metasloit-framework in optional gemspecs

MSP-11578

Optional gemspecs should depend on the minimal metasploit-framework
because they don't work without metasploit-framework's code.
