gexp: Add #:guile parameter to ‘gexp->file’ and ‘scheme-file’. 

This brings ‘gexp->file’ in line with its documentation and mirrors
what’s done for ‘gexp->script’ and ‘program-file’.

Fixes <https://issues.guix.gnu.org/69401>.

* guix/gexp.scm (gexp->file): Add #:guile, as was already documented.
(<scheme-file>)[guile]: New field.
(scheme-file): Add #:guile.
(scheme-file-compiler): Honor ‘guile’ field.
* tests/gexp.scm ("gexp->file")
("gexp->file + file-append", "gexp->file + #:splice?")
("gexp->file, cross-compilation")
("gexp->file, cross-compilation with default target")
Add #:guile to ‘gexp->file’ calls.
("gexp-modules deletes duplicates")
("gexp->derivation & with-imported-module & computed module")
("gexp->derivation & with-extensions", "scheme-file"): Likewise for
‘scheme-file’ calls.
