Branislav Kontur 5cdd819ed2 [xcm] Small enhancements for NetworkExportTable and xcm-builder (#1848 )

## Summary

This PR introduces several enhancements.

The current implementation of `NetworkExportTable` lacks remote location
filtering support beyond `NetworkId` lookup. To provide more control and
granularity, it's essential to allow configuration for bridging to
different consensus `NetworkId` while restricting access e.g. to
particular remote parachains.

Additionally, the `StartsWith` and `Equals` and
`StartsWithExplicitGlobalConsensus` helper functions, which are in
active use, are moved to the `xcm-builder` and `frame_support` modules
for better code organization.

Adds a new `LocationWithAssetFilters` filter to enable location-based
and asset-related filtering. This filter is useful for configuring the
`pallet_xcm` filter for
[XcmTeleportFilter](https://github.com/paritytech/polkadot-sdk/blob/master/polkadot/xcm/pallet-xcm/src/lib.rs#L212)
and
[XcmReserveTransferFilter](https://github.com/paritytech/polkadot-sdk/blob/master/polkadot/xcm/pallet-xcm/src/lib.rs#L216)
to restrict specific assets.

Furthermore, the `BridgeMessage` fields are not accessible outside of
`xcm-builder`, limiting the ability to create custom logic dependent on
it.

Assets Parachain

Implementation of Asset Hub, a blockchain to support generic assets in the Polkadot and Kusama networks. Asset Hub was formerly known as "Statemint".

Asset Hub allows users to:

Deploy promise-backed assets, both fungible and non-fungible, with a DOT/KSM deposit.
Set admin roles to manage assets and asset classes.
Register assets as "self-sufficient" if the Relay Chain agrees, i.e. gain the ability for an asset to justify the existance of accounts sans DOT/KSM.
Pay transaction fees using sufficient assets.
Transfer (and approve transfer) assets.
Interact with the chain via its transactional API or XCM.

Asset Hub must stay fully aligned with the Relay Chain it is connected to. As such, it will accept the Relay Chain's governance origins as its own.

See the article on Asset Hub as common good parachain for a higher level description.

Wallets, custodians, etc. should see the Polkadot Wiki's Integration Guide for details about support.
