#### Problem
HotStorageReader currently not yet has an API to obtain account_offset
#### Summary of Changes
This PR adds HotStorageReader::get_account_offset() which takes
IndexOffset and returns AccountOffset.
#### Test Plan
A new unit-test is included in this PR.
#### Problem
In IndexBlockFormat, both `IndexOffset` and `AccountOffset` parameters
are named `offset` in some functions which could be confusing.
#### Summary of Changes
Renamed `offset` to `index_offset` and `account_offset` to improve
readability.
#### Problem
#33927 introduced a new type AccountOffset, but HotStorageReader
still uses `usize` to access accounts.
#### Summary of Changes
This PR makes HotStorageReader use the new AccountOffset type.
#### Problem
TieredStorage conceptually has different offsets. However, the current code directly
uses the same primitive type for accessing offsets, which is error-prone as one could
easily use one offset to access data that should be accessed with a different offset
type.
#### Summary of Changes
This PR adds IndexOffset type -- a struct for obtaining the ith entry inside the
index-block to obtain account's offset and address.
#### Problem
TieredStorage conceptually has different offsets. However, the current code directly
uses the same primitive type for accessing offsets, which is error-prone as one could
easily use one offset to access data that should be accessed with a different offset
type.
#### Summary of Changes
This PR introduces the AccountOffset type, which allows static-check to on different
type of TieredStorage offsets.
#### Problem
The current tiered-storage code uses "account-index" to call index-block.
This could lead to confusion especially as we start giving each offset/position/index a specific type.
#### Summary of Changes
This PR renames all structs/variables that use account-index to refer to index-block.

Revert "Split compute budget instructions process from struct itself (#33513)"
This reverts commit c73bebe984. This
was found to be a consensus breaking change.
* Split compute budget instruction processing from ComputeBudget struct itself, allow compute_budget_instructions be processed elsewhere without having to instantiate ComputeBudget
* updated tests
#### Problem
HotStorageReader currently only implements get_footer(). It does not
have a function to obtain the account meta.
#### Summary of Changes
This PR implements HotStorageReader::get_account_meta_from_offset().
A function that returns the account meta located at the specified offset.
This will be the helper function that will be later used to obtain the account
meta when the offset is available from the index block of a hot storage file.
#### Test Plan
A new test is included in this PR.
#### Problem
HotStorageReader currently doesn't have a test that covers its footer.
#### Summary of Changes
This PR includes a test for HotStorageReader that verifies the footer.
#### Problem
All account storage formats are required to implement both StoredAccountMeta
and ReadableAccount, but the implementation for the hot account format is missing.
#### Summary of Changes
This PR includes hot account format into StoredAccountMeta and ReadableAccount
enum. This will allow the TieredStorageReader in the future PRs to return hot account
format in its `get_account` implementation.
* hash_dedup vec algo

* simplify working_set init with add_next_item
* refactor to remove special case "new" from add_item.
The new change is that, even the new item is the new min, it will still be added to working_set.
This change will make init working_set code simpler and the loop loop check simpler.
Since the item is inserted in at the end of the vector, the cost of push into and pop from the working will be O(1), shouldn't affect performance much.
* comments
* refactor unnamed tuple in working set to SlotGroupPointer type
* use SlotGroupPointer in ItemLocation
* Add Copy traits to avoid explicty call of clone on SlotGroupPointer
* consume next in add_next_item fn (credit to jeff).
note that the old code is still correct, since before call to
add_next_item, we will have already overwritten `next` to correct value.

#### Problem
The TieredStorageFormat field in the TieredStorage is only used in the write path.
#### Summary of Changes
This PR simplifies the handling of TieredStorageFormat by removing its field from
TieredStorage struct but passing via write_accounts().
The program owners pubkeys are constant, no need to reconstruct the
Vec<Pubkey> and Vec<&Pubkey> each time this function runs (every time we
execute transactions).
