Currently, we write each file to the command line, but this can result in
situations where the number of files passed exceeds OS imposed command
line limits. For compilers, we solve this with response files. For
depscan I've chosen to use a JSON list instead. JSON has several
advantages in that it's standardized, there's a built-in python module
for it, and it's familiar. I've also chosen to always use the JSON file
instead of having a heuristic to decide between JSON and not JSON,
while there may be a small performance trade off here, keeping the
implementation simple with only one path is wort it.
Fixes#9129
In Fortran it is common to use capital F in the suffix (eg. '.F90') if
the source file makes use of preprocessor statements. Such files should
probably be treated like all other fortran files by meson.
Case insensitivity for suffixes was already implemented several places
in meson before this. So most likely, the few places changed here were
oversights anyway.
