4e32271e - [AArch64][SME] Add diagnostics for SME attributes on lambda functions (#121777)

[AArch64][SME] Add diagnostics for SME attributes on lambda functions (#121777) CheckFunctionDeclaration emits diagnostics if any SME attributes are used by a function definition without the required +sme or +sme2 target features. This patch moves these diagnostics to a new function in SemaARM and also adds a call to this from ActOnStartOfLambdaDefinition.
