BACM — Remove category and categorization from the specification

This issue was originally raised in BACM-17 which was proposed to be closed by BACM-54. However, the specification still references meta-classes no longer in the model (e.g. ValueCategory in 7.2.3.1). These references should be replaced.

Makes changes to document shell docx and the EA model to eliminate the terms and concept

Change the document shell docx to eliminate mentions of ValueCategory and categorizes. Regenerate the text documentation from the model and replace the affected sections of the document (Capability and Customer) with the new sections.
