{dev-lang,sys-devel}/rust*: add 1.88.0_beta20250526

This is our first beta for 1.88.0, corresponding to beta.4 upstream.
It is also the first release where `beta` and `live` ebuilds get their
patches from gitweb rather than ${FILESDIR}.

Changes:

  - in line with upstream changes, `config.toml` has been renamed to
    `bootstrap.toml`.
  - `*bootstrap.toml` has `change-id = "ignore"` added to suppress
    warnings that are not useful to downstream.
  - after discussion with upstream `x.py` verbosity reduced to `-v`.
  - restrictions on building beta with only the last stable have been
    dropped, these can be restored if required.
