This patch builds on previously submitted SVE patches regarding expedited register set and per thread register infos. (D82853 <https://reviews.llvm.org/D82853> D82855 <https://reviews.llvm.org/D82855> and D82857 <https://reviews.llvm.org/D82857>)
We need to resize SVE register based on value received in expedited list. Also we need to resize SVE registers when we write vg register using register write vg command. The resize will result in a updated offset for all of fpr and sve register set. This offset will be configured in native register context by RegisterInfoInterface and will be updated by GDBRemoteProcess and GDBRemoteRegisterContext.
A follow up patch will provide a API test to verify this change.
