* Remove invalid dependency on FLATBUFFERS_GENERATE_HEADERS_SCHEMAS
add_dependencies() is for targets.
CMake 4.2.0 fails because of this (it shouldn't crash though, but that's another topic). See https://gitlab.kitware.com/cmake/cmake/-/issues/27415
* Use FLATC_TARGET

The generation of the library interface supplied by this function only
works within the same directory as that the target was defined. By
adding a custom target named GENERATE_<TARGET> now also interface files
will be generated by making a target dependend on the generate target.
Example:
/CMakeLists.txt
set(MY_INCL_SRC ${CMAKE_CURRENT_SOURCE_DIR}/fbs/my_incl.fbs)
flatbuffers_generate_headers(TARGET my_incl
SCHEMAS ${MY_INCL_SRC})
add_subdirectory(app)
/app/CMakeLists.txt
add_executable(app src/test.cpp)
target_link_libraries(app my_incl)
add_dependencies(app GENERATE_my_incl)

* BuildFlatbuffers.cmake: add verbose on build
* BuildFlatbuffers.cmake: properly add *.fb.* files with --grpc argument
When "--grpc" argument is provided as an extra flag, resulting grpc files
should be added as part of the interface library.
This prevent adding .fb.cc files manually to the build.
V2: fix dependency on grpc files
This option was in an earlier revision of flatbuffers_generate_headers
but was lost while refactoring by mistake. We have it as a function
argument rather than one of the optional flags so that we can use it to
inform the rule where to place the generated headers, so that the file
location matches the prefix that will be added to the filenames in the
generated files.
Also fixed some of the documentation in the file.
flatbuffers_generate_headers is a function that can be used to generate Flatbuffers headers and binary headers. It uses named argument flags to wrap all the flags relevant to C++ header generation that flatc uses. It generates an interface library that can be added as a dependency of other targets.
flatbuffers_generate_binary_files is a function that can be used to generate Flatbuffers binaries. It uses named argument flags to wrap all the flags relevant to C++ binary generation from JSON file that flatc uses. It generates an interface library that can be added as a dependency of other targets.
