all: add missing SPDX license to all files

Convert the old ".reuse/dep5" format to REUSE.toml format using
"reuse convert-dep5" command.

For generated files, add the ".license" file.

Using "reuse annotate ..." it automatically add empty line after
"SPDX-FileCopyrightText:", and it also put "SPDX-FileCopyrightText" above
the "SPDX-License-Identifier".

Now, this project is compliant with version 3.3 of the REUSE
Specification.
