[libc++] Adds more forward declaration headers. The module validation script of D144994 validate whether the contents of an include match its module. An include is the set of files matching the pattern: - foo - foo/*. - __fwd/foo.h Several declarations of the stream headers are in the header iosfwd. This gives issue using the validation script. Adding iosfwd to the set of matching files gives too many declarations. For example when validating the fstream header it will pull in declarations of the istream header. Instead if writing a set of filters the headers are granularized into smaller headers containing the expected declarations.

[NFC][libc++] Moves ios_base's forward declaration. (#88027) According to our synopsis it belonged to ios_fwd. This is not true in the C++11 version of the Standard, I did not validate against C++98. Moving this to ios's forward where it's declared in the standard allows removing a module quirk. An earlier removal of std::vectors forward declaration allows to remove all quirks for the iosfwd module part. Since iosfwd includes __fwd/ios.h this does not change the required includes.
