[NFCI] More TypeCategoryImpl refactoring.

[jgorbe]

Summary

The main aim of this patch is to delete the remaining instances of code
reaching into the internals of TypeCategoryImpl. I made the following
changes:

• Add some more methods to TieredFormatterContainer and TypeCategoryImpl to expose functionality that is implemented in FormattersContainer.

• Add new overloads of TypeCategoryImpl::AddTypeXXX to make it easier to add formatters to categories without reaching into the internal FormattersContainer objects.

• Remove the GetTypeXXXContainer and GetRegexTypeXXXContainer accessors from TypeCategoryImpl and update all call sites to use the new methods instead.
