Update active version and comparison configuration to Python 3.15.0. Preserve the alpha implementation status, actual bytecode format, and existing libraries pending separate migration. Align generated library-upgrade workflow pins without changing permissions or actions.

crates/vm/build.rs wrote every environment variable of the build
process into OUT_DIR/env_vars.rs, and _sysconfigdata included that file
into build_time_vars. All build-machine environment variables ended up
as string literals in the binary and were readable at runtime through
sysconfig.get_config_vars().
Remove the dump and the include, and drop the now unused itertools
build-dependency. build_time_vars keeps only the explicit entries.

`version.rs` essentially consists of constants that can be baked in at
compile time. I moved most of `version.rs` to `build.rs`. The constants
are passed via rustc's environment then stored in the binary.
`sys.version_info` and `sys.implementation` are two different versioning
schemes. `version_info` refers to the target Python version while
`implementation` refers to the implementation version.
For RustPython, `version_info` should be 3.14 because it currently
targets Python 3.14. This was correct and remains unchanged.
`implementation`, however, should be set to RustPython's version. I
updated the code to correctly get RustPython's version from the
environment. I also ensured values are hard coded at build time which
reduces the overall code that needs to be run at runtime as well as
removes some unneeded allocations.
Closes: #7770
