Create 64K page size GCP kernel for ARM

[Ian Whitfield]

SRU Justification

[Impact]
A 64k page size flavor was requested by Google.

[Fix]
Add new flavor and configs for 64k page size on arm64.

[Test Plan]
Compile and boot tested. $(getconf PAGE_SIZE) evaluates to 65536.

[Regression Potential]
This is a packaging change which introduces a new flavor, so there is
very low chance of regression. The new flavor can be verified to be 64k
page size through the getconf command.

This bug is awaiting verification that the linux-gcp/6.8.0-1023.25 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-noble-linux-gcp' to 'verification-done-noble-linux-gcp'. If the problem still exists, change the tag 'verification-needed-noble-linux-gcp' to 'verification-failed-noble-linux-gcp'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.
