Add negated dependency support

[adamj88]

Currently, you can specify a patch to apply when a specific composer package is installed using the @depends metadata in a patch file:

@depends magento/module-base:2.4.7

However, you cannot do the reverse of this, apply a patch if another package isn't present.

This PR adds support for this feature, with the following syntax:

@depends !magento/module-base # patch when magento/module-base is not installed
@depends !magento/module-base:>=2.4.7-p6 # patch when magento/module-base is not >=2.4.7-p6

A use case I have is that there is code added to a package, which depends on another that we do not want to use. Subsequently, we use a composer to remove it, however, we also need to patch the module which depends on it to remove any code referencing it.

Thank you for the contribution! I've been checking the changes and so far it's looking good. I've been also updating the testsuite with new cases to confirm these changes specifically, these are so far in https://github.com/vaimo/composer-patches/tree/feature/pr-129-tests. Unfortunately not able to finish checking this during today and then I will be unavailable for two weeks, so there will be delay getting these changes forward. Apologies for that!
