HIVE-27094: Support of big numbers conversions

[NarekDW]

What changes were proposed in this pull request?

Add support for converting big numbers between different radixes, without an overflow.

For example such a query:

SELECT
  conv(9223372036854775807, 36, 16),
  conv(9223372036854775807, 36, -16),
  conv(-9223372036854775807, 36, 16),
  conv(-9223372036854775807, 36, -16)
FROM src tablesample (1 rows); 

Should give a correct result, like:

12DDAC15F246BAF8C0D551AC7   12DDAC15F246BAF8C0D551AC7  D2253EA0DB945073F2AAE539   -12DDAC15F246BAF8C0D551AC7

Why are the changes needed?

Add support for converting big numbers between different radixes, without an overflow.

Does this PR introduce any user-facing change?

Yes, it allows users to convert big numbers without an overflow among different bases.

How was this patch tested?

By existing unit tests + added an additional test case TestUDFConv

Also I tested it on my local machine with JMH and it works faster about 2 times.

Hi guys, it's my first contribution to the hive and I see that CI fails, but seems it is not because of tests or code related issue...
I see such a log in Jenkins:

...
[2023-02-18T21:01:35.667Z] waiting for oracle to be available...
[2023-02-18T21:06:42.458Z] timeout reached before the port went into state "inuse"
script returned exit code 1

Let me know if something is wrong here, please.

This timeout error can be ignored, please check other failed tests in your Tests page.

@wecharyu thank you for the support. Yep, my bad, there was a bug. I've fixed it and added additional unit tests in the TestUDFConv class.
