fuzz: update harness for ifcopenshell::file rename

Browse Source 
ifcviewer-wgpu renamed IfcParse::IfcFile to ifcopenshell::file (header
moved to ifcparse/file.h) and Base::toString to Base::to_string. Update
the harness and README to match; verified with a syntax-only compile
against this branch's headers.

# ifcparse_fuzzer
A libFuzzer harness for `IfcParse::IfcFile`. It parses fuzzer input entirely
A libFuzzer harness for `ifcopenshell::file`. It parses fuzzer input entirely
in-memory (no subprocess, no temp files), then walks every parsed instance
and calls `toString()` on it to force full lazy attribute evaluation -
IfcOpenShell only tokenizes/evaluates on demand, so just constructing
`IfcFile` barely exercises the parser.
and calls `to_string()` on it. Constructing the file already tokenizes,
type-checks, and resolves every attribute of every instance, so
`to_string()` mainly adds coverage of the reserialization/formatting code
path rather than the parser itself.
Disabled by default (`BUILD_FUZZERS=OFF`); building it needs Clang, not GCC.
