emit diagnostic when a key contains different parameters than its value

[earloc]

As a developer, I want to get notified when e resource-key contains more or less parameters than a value of one of the localized resources, in order to prevent runtime-errors after modifying translations.

example1 - too few parameters

the following content of a resx-file should produce a diagnostic The resource-key 'Hello {user:s}, it is {today:d}' of resource 'SomeResource.resx' specifies 1 parameter(s) more, than it´s current value.

//SomeResource.resx

<data name="Hello {user:s}, it is {today:d}" xml:space="preserve">
 	<value>Hello {0}</value>
 </data>

example2 - too many parameters

the following content of a resx-file should produce a diagnostic The resource-key 'Hello {user:s}' of resource 'SomeResource.de-DE.resx' specifies 1 parameter(s) less, than it´s current value.

//SomeResource.de-DE.resx

<data name="Hello {user:s}}" xml:space="preserve">
 	<value>Hello {0}, today is {1}</value>
 </data>

example3 - parameters type mismatch in format-string

the following content of a resx-file should produce a diagnostic The parameter ' {user:s}' of resource-key 'Hello {user:s}, it is {today:d}' of resource 'SomeResource.en-US.resx' is being formatted with an incompatible format '{0:yyyyDDmm}' .

//SomeResource.en-US.resx

<data name="Hello Hello {user:s}, it is {today:d}" xml:space="preserve">
 	<value>Hello '{0:yyyyDDmm}, today is {1}</value>
 </data>

All of the above samples should emit a designated diagnostic TR-XXXX with appropriate explanations
