bunch of fixes/changes to make packages build

[henderkes]

What does this PR do?

• fix removal of directories with symlinks to directories
• add mysqlnd_parsec and mysqlnd_ed25519, closes mysqlnd_parsec #1000
• remove grpc library from grpc ext dependencies
• temporary swoole patch (remove when 6.2.0 releases!)
• don't build addons explicitly
• look for pkgconfig files in all PKG_CONFIG_PATHs so we don't build stuff when a system lib exists and we explicitly want to link against it
• download --update functionality, can download multiple php versions at once

Use it externally in v2: bin/spc build --build-cli bcmath -P a.php

// a.php
if (preg_match('/after-library\[(.*)\]-build/', patch_point(), $match)) {
    $lib_name = $match[1];
    FileSystem::removeDir(SOURCE_PATH . '/' . $lib_name);
}

v3 will mark this as deprecated, using #BeforeStage and #AfterStage attribute instead. But removal will be performed in v4 (will be a long time)

That's not working FYI.

I'm silly. Forgot <?php...

Swoole fails with 8.5.1 despite the patch.

Libwebp fails on alma 8 despite the check succeeding...

And I need another vacation. The composer update before push failed because it failed to remove go package stuff in pkgroot. The bugs actually seem fixed.

[henderkes]

Everything builds now, except for the macos intel failure, I guess.

Looks like it's a JIT bug on x86_64 mAC05.

Upstream issue here: php/php-src#20767 . Looks like we will need to exclude clang version manually here or use homebrew llvm instead.

Swoole is broken on 8.5 until 6.2 release. Nothing we can realistically do there except manually using custom source option for download.

Keeping this PR frozen but open until Swoole releases 6.2. We don't need to add a patch for a dev version, I just need it to build swoole extension for packages.

Upstream issue here: php/php-src#20767 .

That will be fixed soon, we don't need to patch for it.
