[flang] Do not create .f18.mod files for each compiled module (#85249)

Browse Source 
The default CMake scripts had a copy operation to copy a compiled `.mod`
file to also be available with suffix `.f18.mod`. This seems no longer
needed. Also updated ModFiles.md to point to `-module-suffix`.

The disadvantage of using the same name as other compilers is that it is not
clear which compiler created a `.mod` file and files from multiple compilers
cannot be in the same directory. This could be solved by adding something
between the module name and extension, e.g. `<modulename>-f18.mod`.
between the module name and extension, e.g. `<modulename>-f18.mod`. If this
is needed, Flang's fc1 accepts the option `-module-suffix` to alter the suffix
used for the module file.
