Increase build performance w/ Gradle upgrade to 7.4

[am357]

Issue #, if available: 538

Description of changes:
See the attached issue for motivation.

This commit contains the following changes:

1. Required settings for parallelizing test executions for each sub-project.
2. Changes for removing blocking deprecated Gradle settings for upgrading Gradle to 7.4
3. Gradle 7.4 upgrade:
   In addition to other fixes, to be able to use features like File System Watching by default:
   https://docs.gradle.org/current/userguide/performance.html#file_system_watching
4. Enable parallel Gradle build and build cache:
   https://docs.gradle.org/current/userguide/build_cache.html
5. Plugin upgrade:
   As part of upgrade removing the dependency to jcenter repository.

With these changes, apart from parallelizing builds and test executions, our major gain is in builds after the first build. This is because as appose to the current situation, the subsequent build times are dependent to the amount of incremental changes we make between each build. For example in the following, the second build is after making no changes to the first build:

➜  partiql-lang-kotlin git:(improve-build-performance) ./gradlew build

> Task :lang:generatePigDomains
pig: universe file: /Users/maymandi/workplace/maymandi/partiql-lang-kotlin/lang/resources/org/partiql/type-domains/partiql.ion
pig: output file  : /Users/maymandi/workplace/maymandi/partiql-lang-kotlin/lang/src/org/partiql/lang/domains/partiql-domains.kt
pig: parsing the universe...
pig: permuting domains...
pig: applying Kotlin pre-processing
pig: applying the Kotlin template...
pig: universe generation complete!

> Task :lang:compileTestKotlin

Daemon will be stopped at the end of the build after running out of JVM memory

Several build.gradle files have:

        xml.required.set(false)
        html.required.set(true)
        xml.required.set(false)

Where the two xml... lines seem to be duplicates.

Nice improvement! I was getting ~5 min for each local build previously. Now I'm getting around ~3.5 min.

Have the same comment Josh had provided in his review. Otherwise looks good
