Phpunit 10 and Phpstan 1.11

Dependabot suggested some changes this month which required an unusual effort to implement successfully. With the elimination of Php 8.0 as a supported environment, it became possible to use Phpunit 10 rather than 9. Among other considerations, the configuration file for Phpunit is changed. I preserved the Phpunit 9 version under a different name. Aside from the configuration change, several other changes needed to be made to accommodate the change:
- Fix #3993. A peculiar problem indeed. One of the reporters said it had something to do with mocking, but I couldn't duplicate it. But Phpunit 10 revealed the problem in one test (Reader/Xlsx/AutoFilterTest), and that was sufficient for me to apply the trivial source code change to Worksheet/Worksheet.
- Some extra stringency on data providers required extra work in Calculation/CalculationFunctionListTest.
- There was a misplaced label in Calculation/ParseFormulaTest. Likewise in the data member CellGetRangeBoundaries.
- More stringency required changes to data members Shared/Trend/ExponentialBestFit and Shared/Trend/LinearBestFit.
- Issue3982Test testLoadAllRows seemed to go into a memory-acquiring loop in 10 that was not evident in 9. This particular test uses a lot of memory by design, but was included only to establish a base level for the other tests in that member. I feel it is acceptable to skip it for 10.

Phpstan errors with a new release are not unusual. One of the problems this time around was, however, unusual - it is fixed when Phpstan runs under Php8.3, but not for earlier Php releases. Our tools currently use Php 8.1. It is on my to-do list to get Phpstan and other test tools running under 8.3 before 8.1 goes EOL. There are also some configuration file changes needed for Phpstan.

Php-cs-fixer has been taking an increasingly long time to run. They've added an experimental option to permit it to run its checks in parallel. I've changed its configuration to use that option.
