Fix[2306] - Adds support for Trino UDF

[davyboyhayes]

Fixes #2306
Trino SQL allows you to specify User Defined functions in the WITH clause ahead of a statement. This adds support for this type of statement.

It's almost midnight here, so I will need to do the JMH tests in the morning (~0800 UTC)

jmh {
    includes = ['.*JSQLParserBenchmark.*']
    warmupIterations = 2
    fork = 5
    iterations = 5
    timeOnIteration = '5s'
}

After:

  34.537 ±(99.9%) 1.669 ms/op [Average]
  (min, avg, max) = (31.524, 34.537, 36.699), stdev = 2.228
  CI (99.9%): [32.869, 36.206] (assumes normal distribution)

Before:

  36.172 ±(99.9%) 0.175 ms/op [Average]
  (min, avg, max) = (35.851, 36.172, 36.662), stdev = 0.233
  CI (99.9%): [35.997, 36.347] (assumes normal distribution)
