Build Failure for Walnascar Due to ICU 76 Update

[psaavedra]

The build for Walnascar failed due to a recent update to ICU in OpenEmbedded Core: ef2bd18dd1db7e5f01db76889933bfdbb5415aaf.

This failure is currently acceptable since Walnascar is not yet released. However, we need to resolve this issue to ensure future compatibility.

Error Log Highlights:

In file included from .../unicode/uset.h:1660:21: error: 'ConstChar16Ptr' was not declared in this scope
...
/unicode/uset.h:1763:5: error: 'UnicodeString' does not name a type
...
error: 'ConvertibleToU16StringView' was not declared in this scope

Steps to Reproduce:

1. Attempt to build Walnascar using the latest meta-webkit branch.
2. Observe build failure during the do_compile step for wpewebkit_2.46.4.bb.

Potential Cause: The ICU update introduced changes incompatible with the current WebKit version in the meta-webkit layer.
