[release/8.0.1xx-xcode15.1] [msbuild] Process custom entitlements as …

…if they came from an Entitlements.plist file. (#19955)

We need to process custom entitlements just like if they came from an
Entitlements.plist file - which means replacing terms such as
`$(AppIdentifierPrefix)` and `$(TeamIdentifierPrefix)` with their correct value
depending on the provisioning profile.

Partial fix for #19903.

Backport of #19942
