refactor: use constants from kernel::memory module directly

[giwaov]

Description

Replaces 16 simple push-constant procedures in memory.masm with direct constant imports, following the pattern established in #2221.

Each replaced procedure simply pushes a constant onto the stack:

pub proc get_foo_ptr
    push.FOO_PTR
end

These are now replaced at call sites with:

use $kernel::memory::FOO_PTR
# ...
push.FOO_PTR

This removes unnecessary procedure call overhead while keeping the code clear and direct.

Replaced procedures (16 total)

Procedure	Constant
get_input_vault_root_ptr	INPUT_VAULT_ROOT_PTR
get_output_vault_root_ptr	OUTPUT_VAULT_ROOT_PTR
get_tx_script_root_ptr	TX_SCRIPT_ROOT_PTR

get_partial_blockchain_ptr	PARTIAL_BLOCKCHAIN_PTR
get_partial_blockchain_peaks_ptr	PARTIAL_BLOCKCHAIN_PEAKS_PTR
get_native_account_data_ptr	NATIVE_ACCOUNT_DATA_PTR
get_account_data_length	ACCOUNT_DATA_LENGTH
get_max_foreign_account_ptr	MAX_FOREIGN_ACCOUNT_PTR
get_account_delta_fungible_asset_ptr	ACCOUNT_DELTA_FUNGIBLE_ASSET_PTR
get_account_delta_non_fungible_asset_ptr	ACCOUNT_DELTA_NON_FUNGIBLE_ASSET_PTR
get_output_note_data_offset	OUTPUT_NOTE_SECTION_OFFSET
get_kernel_procedures_ptr	KERNEL_PROCEDURES_PTR
get_link_map_region_start_ptr	LINK_MAP_REGION_START_PTR

Files changed (10)

• memory.masm: Removed 16 push-constant procedures and their doc comments. Updated 2 internal callers (get_native_account_active_storage_slots_ptr, get_native_account_initial_storage_slots_ptr) to use push.NATIVE_ACCOUNT_DATA_PTR directly.
• account_delta.masm: 10 replacements (fungible + non-fungible delta ptrs)
• faucet.masm: 4 replacements (input vault root ptr)
• prologue.masm: 5 replacements (kernel procs, block data, partial blockchain, input vault)
• account.masm: 4 replacements (native account data, account data length, max foreign account)
• link_map.masm: 3 replacements (region start/end, entry size)
• epilogue.masm: 2 replacements (output note section offset, output vault root)
• api.masm: 1 replacement (kernel procedures ptr)
• main.masm: 1 replacement (tx script root ptr)
• tx_script_main.masm: 1 replacement (tx script root ptr)

Closes #2415
