Upgrade to latest polkadot-sdk@1.5 release (#137)

Attached result of `cargo upgrade -v --pinned --incompatible`
[cargo-upgrade-version-bump.log](https://github.com/polkadot-fellows/runtimes/files/13873056/cargo-upgrade-version-bump.log)

E.g.: `frame-support` from `25.0.0` to `27.0.0`

_Note: Encointer was not upgraded (because its pallet references
`polkadot@1.3.0` release)._

## TODO

- [x] fix compilation
- [x] fix integration tests
- [x] fix benchmarks (also try them)
- [ ] patch for `pallet-nomination-pools` migration fix
paritytech/polkadot-sdk#3094
- [x] patch for `xcm-executor` fix
paritytech/polkadot-sdk#3174
- [x] search for `TODO:(PR#137) - wait for xcm-executor patch` (missing
`FrameTransactionalProcessor`)
- [x] check/verify `MaxExposurePageSize = 512` / `MaxNominators = 512`
for Kusama/Polkadot
- [x] check with SRLabs (Jakob)
paritytech-secops/srlabs_findings#327


Closes: #113
