Migrate some uses of Traject TranslationMaps to Rust

The rust binary includes the holdings json, so once we finish
this migration, we will not need these two translation map
files.

```
require 'benchmark/ips'
RubyVM::YJIT.enable
code = 'scsbcul'
Benchmark.ips do |x|
  x.report('rust - location label') { BibdataRs::Marc.location_label(code) }
  x.report('ruby - location label') { Traject::TranslationMap.new('locations')[code] }
  x.compare!
end
Benchmark.ips do |x|
  x.report('rust - library label') { BibdataRs::Marc.library_label(code) }
  x.report('ruby - library label') { Traject::TranslationMap.new('location_display')[code] }
  x.compare!
end
```

```
