Generate fixtures for these test cases for Amsterdam with:

fill -v tests/cancun/eip4844_blobs/test_blobhash_opcode_contexts.py::test_blobhash_opcode_contexts_tx_types --fork Amsterdam

Tests that the BLOBHASH opcode functions correctly when called in different contexts.

• BLOBHASH opcode on the top level of the call stack.
• BLOBHASH opcode on the max value.
• BLOBHASH opcode on CALL, DELEGATECALL, STATICCALL, and CALLCODE.
• BLOBHASH opcode on Initcode.
• BLOBHASH opcode on CREATE and CREATE2.
• BLOBHASH opcode on transaction types 0, 1 and 2.
