ledger-tool: Run rustfmt with format_strings = true

[steviez]

This PR spun out from #34274 per some conversation to consider running the rustfmt on a subset to see if it makes things more manageable.

Problem

Long string literals can cause rustfmt to fail, which results in rustfmt failing to format entire functions. There are several instances of this in ledger-tool, so format these files with wrapped strings so that formatting will apply to functions again.

Summary of Changes

Note that this PR was created by adding format_strings = true to rustfmt.toml; however, this change does NOT persist that rule as the rule would format the entire repo.

While reviewing the diff, I do see some lines that were wrapped that could be candidates for inlining the values in format strings:

solana/ledger-tool/src/bigtable.rs

Line 464 in 4832b4e

error!("confirmed_block_exists() failed from the destination Bigtable, slot: {}, err: {}", slot, err);

However, there are similar instances in lines that are not wrapped, so I'm inclined to defer that

[steviez]

In the other PR, Tyera mentioned that strings like this could get mangled:

first half of the string\
second half of the string

Namely, this would get turned into

first half of the stringsecond of the string

whereas we most likely want

first half of the string second half of the string

due to the lack of a whitespace before the trailing \. Scanning this PR, I didn't see any instances except for the ones she called out, which I fixed in the second commit.

I suggested a couple default reformats to match what I did in solana-cli, but I don't feel strongly about them here. Feel free to merge as-is if you prefer.

No, these are good ones that I missed on my pass through (think my eyes were starting to bleed from doing solana-cli and this one back-to-back haha).
