compile time caching

[SanderMuller]

Caches objects and results that were being recreated on every compilation pass:

• BladeService: Move 8 ReflectionClass/ReflectionMethod instantiations from per-call to constructor
• Directives: Guard 3 preg_replace calls with str_contains checks. Most templates don't contain {{--, @verbatim, or @php
• ComponentSource: Memoize file_get_contents so repeated content() calls don't re-read the file
• Config: Cache realpath() results to avoid repeated syscalls for the same paths

Also adds a compilation benchmark (/benchmark compilation) that measures BlazeManager::compile() throughput directly.

Locally these changes make about a 24-42% compilation speedup compared to main

Note: For the best CI comparison, cherry-pick the benchmark commit (38c6d46) onto main first so the snapshot step can generate a baseline.

Aren't we going to blow up the memory by caching contents of every single component? The ComponentSource objects are being cached in a static property so they're going to remain in memory forever.

Although I think the memory usage will be quite little for 99% of the apps, perhaps it can grow bigger for very large apps using Octane. I've removed the contentCache property and reverted content() to direct file_get_contents().
