Alexandru Croitor 1981682687 CMake: Propagate sanitizer flags to public projects
Ensure that Qt user projects build with sanitizer flags if Qt was
configured with any of the sanitizers enabled.

To compile Qt with sanitizer support enable any of Qt sanitizer
features.

Passing -DECM_ENABLE_SANITIZERS=address to CMake is NOT supported
anymore.

When configuring Qt using CMake directly, pass
    -DFEATURE_sanitizer_address=ON
    -DFEATURE_sanitizer_undefined=ON
instead of
    -DECM_ENABLE_SANITIZERS=address;undefined

When configuring Qt with the configure script pass
    -sanitize address -sanitize undefined
as usual.

QtConfig.cmake now records the sanitizer options that should be
enabled for all consuming projects based on the enabled Qt features.
This applies to internal Qt builds as well as well as tests an
examples.

The recorded sanitizer options are assigned to the ECM_ENABLE_SANITIZERS
variable in the directory scope where find_package(Qt6) is called.
The ECMEnableSanitizers module is included to add the necessary flags to
all targets in that directory scope or its children.

This behavior can be opted out by setting the
QT_NO_ADD_SANITIZER_OPTIONS variable in projects that use Qt and might
be handling sanitizer options differently.
