binman: test: Move remaining test files to test/entry/

Move the remaining 60 or so test files into an entry/ subdirectory.
These cover general entry types and features: entry args, fill, text,
env, compress, replace, template, collection, ELF, overlap, listing,
sections, symlink, TEE OS, and other miscellaneous entries. Drop the
numeric prefixes and update all references.
