Add ext/uri skeleton along with uriparser

[kocsismate]

Relates to #14461 and https://wiki.php.net/rfc/url_parsing_api

[TimWolla]

Did not verify whether the uriparser files match the upstream sources.

These are not currently exported, but exporting the exception CEs might make sense. I suggest to rename them to avoid conflicts.

The following pattern is used by ext/random:

Suggested change

	zend_class_entry *uri_exception_ce;
	zend_class_entry *invalid_uri_exception_ce;
	zend_class_entry *whatwg_invalid_url_exception_ce;
	zend_class_entry *uri_ce_Uri_UriException;
	zend_class_entry *uri_ce_Uri_InvalidUriException;
	zend_class_entry *uri_ce_Uri_WhatWg_InvalidUrlException;

Let's make renames a bit later when the actual content is also added - at least I can then use the IDE to also rename the references. 🤔

@TimWolla I just validated that uriparser matches upstream at commit 019af45951c76415bd7d999313faf5c0e53aea0d

[ndossche]

I'll sign off for today so I'll check tomorrow again (after CI is green)

[kocsismate]

Ah, I've just realized that I have to add back the UriConfig.h that was a manually added file IIRC, because the CMake based build script would have to generate it by default.

[TimWolla]

LGTM.

Verified the uriparser sources against uriparser/uriparser@019af45 with the addition of the UriConfig.h.

[ndossche]

One remark, otherwise lgtm

After the merge, the ability to build PHP in a directory different from the source dir is broken.

@dstogov Arnaud has already created a PR to fix this: #18716 I'm going to merge it now.
