[MAINTENANCE] Remove legacy data format support

ISSUE At one point, the data model stored embargo flags in multiple formats. The data has since been normalized and all ETDs are populated with a TRUE/FALSE boolean value for each embargo flag.

An analysis of the current Solr index confirms this:

has_model_ssim:Etd - 12,652
abstract_embargoed_bsi:* - 12,652
files_embargoed_bsi:* - 12,652
toc_embargoed_bsi:* - 12,652

Further, the *_tesim values have been removed from the index (see supporting data below)

Therefore, we no longer require the datatype fallbacks impelmented to support the non-normalized data.

RESOLUTION Simplify the SolrDocument model by removing obsolete data type spport.
