Add missing XCM benchmarks for ReserveAssetDeposited (#4923)

* Add missing XCM benchmarks for ReserveAssetDeposited

* Check whether checking account is zero before minting

* Try and prevent overflow

* Remove minting currencies into the checking account

* cargo run --quiet --profile=production  --features=runtime-benchmarks -- benchmark --chain=westend-dev --steps=50 --repeat=20 --pallet=pallet_xcm_benchmarks::fungible --extrinsic=* --execution=wasm --wasm-execution=compiled --heap-pages=4096 --header=./file_header.txt --template=./xcm/pallet-xcm-benchmarks/template.hbs --output=./runtime/westend/src/weights/xcm/pallet_xcm_benchmarks_fungible.rs

* Use a smaller divisor

* Mint a smaller amount still

* cargo run --quiet --profile=production  --features=runtime-benchmarks -- benchmark --chain=westend-dev --steps=50 --repeat=20 --pallet=pallet_xcm_benchmarks::fungible --extrinsic=* --execution=wasm --wasm-execution=compiled --heap-pages=4096 --header=./file_header.txt --template=./xcm/pallet-xcm-benchmarks/template.hbs --output=./runtime/westend/src/weights/xcm/pallet_xcm_benchmarks_fungible.rs

* Remove logic for minting assets to the checking account

* Configure a smaller amount of reserve asset used for testing

* Try unwrapping the result of an execution

* Set the origin properly

* Revert "Set the origin properly"

This reverts commit c748a05733173fb7072878c19b10a583675a5f54.

* Update license year
