Data saved in the 'function' column can be too long or have bad encoding

Problem/Motivation

When running unit tests, simpletest saves every test method run, along with the provided data, in the simpletest.function column. This can sometimes lead to MySQL errors, as the data provided can be too long for the 'function' column (varchar, 255) or it can have bad encoding.

Example #1:

Test: Drupal\\Tests\\big_pipe\\Unit\\Render\\BigPipeResponseAttachmentsProcessorTest

Data saved in 'function column: 

Drupal\Tests\big_pipe\Unit\Render\BigPipeResponseAttachmentsProcessorTest->testHtmlResponse with data set "all official attachment types, with random assigned values, even if technically not valid, to prove BigPipeResponseAttachmentsProcessor is a perfect decorator"()

Error: PDOException: SQLSTATE[22001]: String data, right truncated: 1406 Data too long for column 'function'

Example #2:

Test: Drupal\\Tests\\big_pipe\\Unit\\Render\\Placeholder\\BigPipeStrategyTest

Data saved in 'function column: Drupal\Tests\big_pipe\Unit\Render\Placeholder\BigPipeStrategyTest->testProcessPlaceholders with data set "_no_big_pipe absent, session, no-JS cookie present: no-JS BigPipe placeholder used for HTML placeholders — but unsafe method"()

Error: ERROR 1366 (HY000): Incorrect string value: '\xE2\x80\x94 bu...' for column 'function'

Proposed resolution

Set proper encoding on the 'function' data and truncate it if necessary, before saving it.
