Allow to use wildcard for buildinputs.

[Jarod42]

What does this PR do?

Allow to use wildcard for buildinputs.

i.e

buildinputs {"*.extra_inputs"}
-- instead of
-- buildinputs(os.matchfiles("*.extra_inputs"))

How does this PR change Premake's behavior?

Paths which have * now use wilcard instead of being passed as-is.

Are there any associated tests we can add for this?

[Jarod42]

Each generators have some tests for buildinputs (but to test their rules, not wildcard). but I don't think it would be the right place to test each possible kind of value (wildcard, token, absolute path, relative path, ...).

There is missing (generic) tests\api\test_file_kind.lua but it would mostly to test api file than buildinputs.
I can add it.

UTs for api added.
