ARROW-16636: [Rust] Activate several IPC integration tests for rust

[viirya]

arrow-rs has fixed severals integration test failures (apache/arrow-rs#1404):

generate_decimal128_case
generate_interval_case
generate_map_case
generate_non_canonical_map_case
generate_nested_large_offsets_case
generate_nested_dictionary_case
generate_unions_case

And this one passes test without any fix:
generate_extension_case

We should activate these IPC integration tests for rust.

Got the following errors in CI:

################# FAILURES #################
FAILED TEST: nested_large_offsets Java producing,  Rust consuming

FAILED TEST: decimal Rust producing,  Rust consuming

FAILED TEST: union Rust producing,  Rust consuming

Hmm, I ran archery integration --with-cpp=true --with-rust=true locally without any issue. We also don't run Java. I'll look into the difference.

This is epic -- thank you @viirya for looking into this

[viirya]

I'm in business trip this week. I will have more time to look into this in next week.

Regarding the failure FAILED TEST: decimal Rust producing, Rust consuming, it is because Rust performs a decimal check that C++ doesn't. And in the golden file 0.14.1_decimal.gold.json, there are some values failing this check. I can conform that the test can be passed if removing the check in Rust side.

I propose a quick fix at Rust side to remove it, just following C++ Arrow decimal builder.

[viirya]

Yea, FAILED TEST: decimal Rust producing, Rust consuming was fixed now. Continuing looking into remaining two failed cases.

[viirya]

For FAILED TEST: union Rust producing, Rust consuming, proposed the fix at apache/arrow-rs#1789

[viirya]

@alamb All tests are passed now. Please take a look. Thanks.

Amazing work @viirya ❤️

The arrow repo used to have a different way of merging PRs (using a script) -- let me know if you would like to give it a try or if you would like me to. 🎖️

[viirya]

@alamb Thank you. I may rarely touch C++ repo. Please help merging this. If I have more works in this repo in the future, I can catch up it later.

[alamb]

Looking into it

[alamb]

Following the process in https://github.com/apache/arrow/tree/master/dev

Thanks again @viirya -- this is a major step forward
