[SPARK-28071][SQL][TEST] Port strings.sql
## What changes were proposed in this pull request?
This PR is to port strings.sql from PostgreSQL regression tests.
https://github.com/postgres/postgres/blob/REL_12_BETA2/src/test/regress/sql/strings.sql
The expected results can be found in the link:
https://github.com/postgres/postgres/blob/REL_12_BETA2/src/test/regress/expected/strings.out
When porting the test cases, found nine PostgreSQL specific features that
do not exist in Spark SQL:
[SPARK-28076](https://issues.apache.org/jira/browse/SPARK-28076): Support
regular expression substring
[SPARK-28078](https://issues.apache.org/jira/browse/SPARK-28078): Add
support other 4 REGEXP functions
[SPARK-28412](https://issues.apache.org/jira/browse/SPARK-28412): OVERLAY
function support byte array
[SPARK-28083](https://issues.apache.org/jira/browse/SPARK-28083): ANSI
SQL: LIKE predicate: ESCAPE clause
[SPARK-28087](https://issues.apache.org/jira/browse/SPARK-28087): Add
support split_part
[SPARK-28122](https://issues.apache.org/jira/browse/SPARK-28122): Missing
`sha224`/`sha256 `/`sha384 `/`sha512 ` functions
[SPARK-28123](https://issues.apache.org/jira/browse/SPARK-28123): Add
support string functions: btrim
[SPARK-28448](https://issues.apache.org/jira/browse/SPARK-28448): Implement
ILIKE operator
[SPARK-28449](https://issues.apache.org/jira/browse/SPARK-28449): Missing
escape_string_warning and standard_conforming_strings config
Also, found five inconsistent behavior:
[SPARK-27952](https://issues.apache.org/jira/browse/SPARK-27952): String
Functions: regexp_replace is not compatible
[SPARK-28121](https://issues.apache.org/jira/browse/SPARK-28121): decode
can not accept 'escape' as charset
[SPARK-27930](https://issues.apache.org/jira/browse/SPARK-27930): Replace
`strpos` with `locate` or `position` in Spark SQL
[SPARK-27930](https://issues.apache.org/jira/browse/SPARK-27930): Replace
`to_hex` with `hex ` or in Spark SQL
[SPARK-28451](https://issues.apache.org/jira/browse/SPARK-28451): `substr`
returns different values
## How was this patch tested?
N/A
Closes #24923 from wangyum/SPARK-28071.
