Maarten Bent 4fa3b8c276 CMake: Fix the minimum supported version
Change the minimum version to 3.0. Version 2.8.12 has never worked,
because it does not support the VERSION parameter in project().

Replace GREATER_EQUAL comparisons, these are only supported since 3.7.

Move PCH related code to a separate file, and include it after
options.cmake and init.cmake. Because only then the wxBUILD_PRECOMP
variable is fully initialized.

Closes #22312.
