Miguel Ojeda	bc1565efc3	rust: proc-macro2: add README.md ... Originally, when the Rust upstream `alloc` standard library crate was vendored in commit 057b8d2571 ("rust: adapt `alloc` crate to the kernel"), a `README.md` file was added to explain the provenance and licensing of the source files. Thus do the same for the `proc-macro2` crate.

Miguel Ojeda	c2af0e5f02	rust: proc-macro2: remove unicode_ident dependency ... The `proc-macro2` crate depends on the `unicode-ident` crate to determine whether characters have the XID_Start or XID_Continue properties according to Unicode Standard Annex #31. However, we only need ASCII identifiers in the kernel, thus we can simplify the check and remove completely that dependency.

Miguel Ojeda	a9acfceb96	rust: proc-macro2: add SPDX License Identifiers ... Originally, when the Rust upstream `alloc` standard library crate was vendored in commit 057b8d2571 ("rust: adapt `alloc` crate to the kernel"), the SPDX License Identifiers were added to every file so that the license on those was clear. Thus do the same for the `proc-macro2` crate. This makes `scripts/spdxcheck.py` pass.
