all: simplify nested complexity and if blocks ending with a return statement (#21854)
Changes:

    Simplify nested complexity
    If an if blocks ends with a return statement then remove the else nesting.

trie: polishes to trie committer (#21351)
* trie: update tests to check commit integrity

* trie: polish committer

* trie: fix typo

* trie: remove hasvalue notion

According to the benchmarks, type assertion between the pointer and
interface is extremely fast.

BenchmarkIntmethod-12           1000000000               1.91 ns/op
BenchmarkInterface-12           1000000000               2.13 ns/op
BenchmarkTypeSwitch-12          1000000000               1.81 ns/op
BenchmarkTypeAssertion-12       2000000000               1.78 ns/op

So the overhead for asserting whether the shortnode has "valuenode"
child is super tiny. No necessary to have another field.

core: types: less allocations when hashing and tx handling (#21265)
* core, crypto: various allocation savings regarding tx handling

* core: reduce allocs for gas price comparison

This change reduces the allocations needed for comparing different transactions to each other.
A call to `tx.GasPrice()` copies the gas price as it has to be safe against modifications and
also needs to be threadsafe. For comparing and ordering different transactions we don't need
these guarantees

* core: added tx.GasPriceIntCmp for comparison without allocation

adds a method to remove unneeded allocation in comparison to tx.gasPrice

* core/types: pool legacykeccak256 objects in rlpHash

rlpHash is by far the most used function in core that allocates a legacyKeccak256 object on each call.
Since it is so widely used it makes sense to add pooling here so we relieve the GC.
On my machine these changes result in > 100 MILLION less allocations and > 30 GB less allocated memory.

* trie: use crypto.KeccakState instead of replicating code
