Fix [C#] Object API - Invalid Property Name used in UnPackTo for unio… (#7751)
* Fix [C#] Object API - Invalid Property Name used in UnPackTo for union fieldhttps://github.com/google/flatbuffers/issues/7750, also fixes invalid Code generated in WriteJson for Unions named Value. * Test added: new schema union_value_collision.fbs with a Union named Value and a union field named value. The generated C# code now compiles when NetTest.bat. The Code generated with an older flatc.exe didn't compile because of a mismatch of the property name (Value vs. Value_). * branch was not up-to-date with master * BASE_OPTS + CPP_OPTS removed and union_value_collision_generated.h deleted Co-authored-by: Derek Bailey <derekbailey@google.com>
