feat(mainnet): include pallets in define_benchmarks and remove default configs

[peterwht]

Currently, in all our of runtimes, but most importantly in the mainnet runtime we use the default configuration for many pallets #[derive_impl(frame_system::config_preludes::ParaChainDefaultConfig)]. This results in using the default WeightInfo. Furthermore, define_benchmarks excludes most pallets.

In the 2412 release, there is also a new extension benchmark for frame-system. This needs to be added as well (and will be exposed when the default configuration is removed):

• Remove default configurations
• Include pallets in define_benchmarks
• add SystemExtensionsBench | FRAME: Reintroduce TransactionExtension as a replacement for SignedExtension paritytech/polkadot-sdk#3685
• XCM: Configure Weigher using WeightInfoBounds instead of the current configuration using FixedWeightBounds.
