16k: soong: Update DevicePageSizeAgnostic to DeviceNoBionicPageSizeMacro

This is part of a larger change to update the flag
PRODUCT_PAGE_SIZE_AGNOSTIC to PRODUCT_NO_BIONIC_PAGE_SIZE_MACRO.
This is to help clarify that this flag doesn't mean the device
will actually work end-to-end with any page size.

Bug: 312541564
Test:
```
source build/envsetup.sh
lunch aosp_cf_arm64_phone_pgagnostic-trunk-userdebug
m
cat out/soong/build.aosp_cf_arm64_phone_pgagnostic.ninja | grep __BIONIC_NO_PAGE_SIZE_MACRO
```
